According to the exterior angle theorem, the exterior angle that results from stretching a triangle's side is equal to the sum of the dimensions of the triangle's two opposed interior angles.
What is theorem of exterior angles?According to the exterior angle theorem, the exterior angle that results from stretching a triangle side is equal to the sum of the dimensions of the triangle's two opposed interior angles. Three internal angles in a triangle or polygon always add up to 180 degrees. This theorem is applied to each of the outer angles, which total six.
Here,
Given :
With the help of the triangle's well-known features, we can validate the exterior angle theorem.
Think about an ABC.
The total of the three angles is 180 degrees (angle sum property of a triangle) ——- Equation 1: (A+B)/180 ——- Example 2 (rewriting equation 1)
e = 180 - c
——- Equivalent 3 (linear pair of angles)
Equation 3 may be solved for by substituting the value of c.
e = 180 - [180 - (a + b)]
e = 180 - 180 + (a + b)
e = a + b.
=> m∠A = m∠G
=> m∠DMG > m∠A
So , its proven that:
=> m∠DMG > m∠G
and
=> A-D-M
So,
AD = DM
=> AD <AM

What is the acute angle?Angles that are less than 90° are considered acute, and a protractor can be used to measure these angles. Acute, Obtuse, Right, Straight, Reflex, and Full Rotation are the names of the basic angles. Two rays are joined at their ends to create the geometric shape known as an angle. Typically, angles are expressed in terms of degrees. A triangle that has each angle less than 90 degrees is said to be acute.Triangles are not sharp even when one of their angles is 90 degrees. The fact that all angles (60°) in an equilateral triangle are less than 90° ensures that it is always sharp.If you need to see the algebra, the acute angles in a right triangle are complementary, adding to 90 degrees:

A baker will supply 22 jumbo cinnamon rolls to a cafe at a price of $3.46 each. If she is offered $3.16, then she will supply 2 fewer rolls to the cafe. The cafe's demand for jumbo cinnamon rolls is given by p = D(x) = -0.25x + 6.56. What is the equilibrium point?
Answers
If a baker will supply 22 jumbo cinnamon rolls to a cafe at a price of $3.46 each. the equilibrium point is: 20 rolls and the price is $4.86.
How to find the price?The equilibrium point is where the supply and demand curves intersect, representing the price and quantity where the market is in balance.
Let's call the number of rolls the baker supplies x.
At the original price of $3.46 each, she supplies 22 rolls.
When offered $3.16, she will supply 2 fewer rolls, so she supplies x = 22 - 2 = 20 rolls.
We can use the demand equation to find the corresponding quantity demanded for each price:
p = D(x) = -0.25x + 6.56
D(22) = -0.25 * 22 + 6.56 = 4.56
D(20) = -0.25 * 20 + 6.56 = 4.86
The intersection of the two points (22, 4.56) and (20, 4.86) gives us the market equilibrium quantity and price.
So the equilibrium point is:
x = 20 rolls
p = $4.86 each.

Hi! Can someone please help with this question? I'm really confused on how exactly to find the force of magnitude
Answers
The magnitude and direction of the force C are 93.853 pounds-force and 281.237°, respectively.
How to find the magnitude and direction of a force in a 3-vector system
In this problem we find the case of a system at equilibrium and formed by 3 vectors, of which we must determine the magnitude and direction of a force must be determined. Vectors are described by two features: (i) Magnitude, (ii) Direction.
The magnitude is obtained by Pythagorean theorem:
F = √(x² + y²)
The direction is determined by inverse trigonometric functions:
θ = tan⁻¹ (y / x)
Besides, the system can be described physically by Newton's laws and mathematically by vector sum:
F₁(x, y) + F₂(x, y) + F₃(x, y) = (0, 0)
First, determine the vector associated to force C:
F₃(x, y) = - F₁(x, y) - F₂(x, y)
F₃(x, y) = - (- 92 · cos 45°, 92 · sin 45°) - (54 · cos 30°, 54 · sin 30°)
F₃(x, y) = - (- 46√2, 46√2) - (27√3, 27)
F₃(x, y) = (46√2, - 46√2) - (27√3, 27)
F₃(x, y) = (46√2 - 27√3, - 46√2 - 27)
Second, calculate the magnitude of force C:
F₃ = √[(46√2 - 27√3)² + (- 46√2 - 27)²]
F₃ ≈ 93.853
Third, determine the direction of force C:
θ = tan⁻¹ [(- 46√2 - 27) / (46√2 - 27√3)]
θ ≈ 281.237°

Answer:
F₃ = 94 lb at 78.8° below the +x axis
Step-by-step explanation:
You want the magnitude of force F₃ that makes the sum of forces be zero.
Sum of forcesAs you have already noted, the sum of forces is zero when the system is at equilibrium.
F₁ +F₂ +F₃ = 0
F₃ = -(F₁ +F₂)
The forces F₁ and F₂ can be added by adding their horizontal and vertical components.
F₁ = 92(cos(135°), sin(135°)) ≈ (-65.0538, 65.0538)
F₂ = 54(cos(30°), sin(30°)) ≈ (46.7654, 27)
Then the sum of forces is ...
F₁ +F₂ ≈ (-18.2884, 92.0538) . . . . . sum of corresponding parts
MagnitudeAs we noted above, F₃ is the opposite of the sum, so is ...
F₃ = (18.2884, -92.0538)
The magnitude is found using the Pythagorean theorem:
|F₃| = √(18.2884² +(-92.0538)²) ≈ √8808.3677 ≈ 93.8529
The magnitude of F₃ is about 94 lb.
DirectionThe components of F₃ tell you the force is in the 4th quadrant. The ratio of the x- and y-components is the tangent of the angle:
θ = arctan(y/x) = arctan(-92.0538/18.2884) = arctan(-5.03345)
θ ≈ -78.763°
In the first attachment, the sum of forces F₁ +F₂ is shown by the black arrow. The direction of F₃ will be the opposite of that arrow's direction, so will be down to the right, about 78.8° below the +x axis. The second attachment shows the magnitude and direction of F₃, where 0° is the direction of the +x axis.
__
Additional comment
For finding the magnitude of the sum of two forces, the Law of Cosines is another way to do it. To use that, you need to know the angle between the two forces. That's the angle at lower right inside the triangle shown in the first attachment. It is 75°. Then the magnitude is ...
|F₃| = √(54² +92² -2·54·92·cos(75°)) ≈ √8808.37 ≈ 93.853 . . . . lb
This math can be simpler than working with the x- and y-components of the forces.
The angle of F₃ is another matter. Finding that requires solving the force triangle for one of the other interior angles, then adding the angles in the appropriate way.
For example, the angle at the origin can be found from the Law of Sines as ...
α = arcsin(92/93.853·sin(75°)) ≈ 71.237°
Adding this to the angle of the red vector (30°) gives the resultant angle relative to the +x axis of 101.237°. The direction of F₃ is opposite this, so is ...
101.237° -180° = -78.763° . . . . as above
As you can see from the attachments, a vector calculator or spreadsheet is a useful tool for finding sums of forces from their magnitude and direction.
Just to be clear, the conversion between polar and rectangular forms is ...
(x, y) = r(cos(θ), sin(θ))
r = √(x² +y²)
θ = arctan(y/x) . . . . . with attention to quadrant
Spreadsheets and some calculators have an ATAN2(x, y) function that takes the signs into account when it computes the angle. When working with angles, make sure the calculator's angle mode is set to degrees or radians appropriately. (Spreadsheets usually use radians.)
It is day 8 and you are getting hungry. Since hunting/fishing have not been successful so far, you decide to eat ants for protein. 100 grams of ants gives enough protein as an egg. How many ants is this if one ant is between 1 - 5 mg? (Give a range of values)
Answers
The range of ants to eat is 20,000-1,00,000 ants.
What is range?The difference between the highest and lowest values for a particular data collection is the range in statistics. For instance, the range will be 10 - 2 = 8 if the provided data set is 2, 5, 8, 10, and 3.
As a result, the range may alternatively be thought of as the distance between the highest and lowest observation. The range of observation is the name given to the outcome. Statistics' range reflects the variety of observations.
The answer is given below:
If each ant is of 1 mg:
1g = 1000 mg = 1000 ants
100g = 100000 mg = 100000 ants
=> Maximum 105 ants
Now if one ant is of 5 mg:
1g = 1000mg = 1000/5 = 200 ants
100g = 20000 ants
Minimum 20,000 ants
Hence the range of ants to eat is 20,000-1,00,000 ants.

in the diagrams below parallel lines I and m are crossed by transversal n at an 108 degree angle as shown. which set of angles are supplementary to the 108° angle?
Answers
Our assumption that m II is intersected by a transversal n is wrong, thus none of the set of angles are supplementary to 108°.
What is transversal?A transversal in geometry is a line that intersects two other lines in the same plane at two different locations. It is possible to determine whether two or more other lines in the Euclidean plane are parallel by using transversals.
A line that crosses two lines in the same plane at two different geometric locations is referred to as a transversal. The angles that result from a transversal crossing of two lines in pairs can be successive internal angles, matching angles, or alternate angles.
The transversal angles. There are numerous angles created when a transversal splits two parallel lines. They are referred to as transversal angles.
Given, ∠1 = 70°
∠7 = 80°
Vertically opposite angles are equal.
∠1 = ∠3
⇒ ∠1 = ∠3 = 70°
As per the diagram, line 1 is intersected by line n.
Vertically opposite angles are equal.
∠5 = ∠7
=> ∠5 = ∠7 = 80°
Let m II l is intersected by a transversals n.
Then the pair of corresponding angles should be equal. i.e.,
∠1 = ∠5
= ∠3 = ∠7
but ∠1 = 70
and ∠5 = 80°
Therefore, our assumption that m II is intersected by a transversal is wrong.

The median of the data set is 75.80, rounded to two decimal places.
The mean of the data set can be calculated by adding up all the values and dividing by the number of values.
The formula is:
mean = (sum of all values) / (number of values)
For the given data set, mean = (59.8 + 61.4 + 69 + 71.2 + 78.7 + 83.5 + 89.6 + 94.1 + 84 + 75.2 + 79.7 + 83.6 + 74.8 + 74 + 83.3 + 73.8 + 90 + 68.3 + 71.7 + 74.2 + 69.3 + 68.5 + 71.3 + 78.5 + 73.2 + 91.4 + 78.7 + 56.4 + 73 + 65.6 + 69.9 + 73.8 + 80.1 + 78.7 + 75.8 + 66.7 + 79.7 + 66 + 73 + 85.3 + 72.1 + 78.5 + 79.9 + 75.6 + 71.3 + 69.6 + 58.6 + 64.3 + 63.2 + 79.9 + 70.1 + 80.4 + 88.2 + 79.4 + 74.6 + 65.2 + 70.6 + 77 + 73.2 + 81.5 + 83.3 + 77 + 82 + 78.5 + 75.4 + 78.5 + 73.6 + 86.8 + 74.4 + 65.2) / 60 = 6288.6 / 60 = 104.81
So, the mean of the data set is 104.81, rounded to two decimal places.
The median of the data set can be calculated by arranging the values in ascending order and finding the middle value. If there are an odd number of values, the median is the middle value. If there are an even number of values, the median is the average of the two middle values.
For the given data set, the median can be found as follows:
56.4 58.6 63.2 64.3 65.2 65.6 66 66.7 68.3 68.5 69 69.3 69.6 69.9 70.1 70.6 71 71.3 71.7 73 73 73.2 73.6 73.8 74 74 74.2 74.4 74.6 75.2 75.4 75.6 75.8 76.7 77 78 78.5 78.5 78.5 78.7 79 79.4 79.7 79.7 79.9 80.1 80.4 81.5 82 83 83.3 83.3 83.5 83.6 84 85.3 86.8 89.6 90 91.4 94.1
The median is 75.8.

A new cruise ship line has just launched 3 new ships: the Pacific Paradise, the Caribbean Paradise, and the Mediterranean ParadiseThe Caribbean Paradise has 16 more deluxe staterooms than the Pacific Paradise. The Mediterranean Paradise has 28 fewer deluxe staterooms than four times the number of deluxe staterooms on the Pacific Paradise Find the number of deluxe staterooms for each of the ships if the total number of deluxe staterooms for the three ships is 1176
ANSWERS MUST ADD UP TO 1176
Answers
Answer:
Pacific Paradise = 198 deluxe stateroomsCaribbean Paradise = 214 deluxe stateroomsMediterranean Paradise = 764 deluxe stateroomsCheck: 198+214+764 = 1176 total rooms
==========================================================
Explanation
I'll define these variables:
p = number of deluxe staterooms on Pacific Paradisec = number of deluxe staterooms on Caribbean Paradisem = number of staterooms on Mediterranean ParadiseWe have these given facts:
The Caribbean Paradise has 16 more deluxe staterooms than the Pacific Paradise. The Mediterranean Paradise has 28 fewer deluxe staterooms than four times the number of deluxe staterooms on the Pacific Paradise The total number of deluxe staterooms for the three ships is 1176Fact 1 allows us to form the equation c = p+16
Fact 2 allows us to form the equation m = 4p-28
Fact 3 leads to the equation p+c+m = 1176
Let me know if you have any questions about how I formed the equations.
---------------------
The system of equations is:
[tex]\begin{cases}c = p+16\\m = 4p-28\\p+c+m = 1176\\\end{cases}[/tex]
Notice how the first two equations have the variable p on the right hand side, and no other variable. We'll use this to apply substitution and solve for p.
p+c+m = 1176
p+(p+16)+m = 1176 ... replace c with p+16
p+(p+16)+(4p-28) = 1176 ... replace m with 4p-28
6p-12 = 1176
6p = 1176+12
6p = 1188
p = 1188/6
p = 198
Use this value of p to find the other variables.
c = p+16 = 198+16 = 214
m = 4p-28 = 4*198-28 = 764
---------------------
Summary:
We found that p = 198, c = 214, and m = 764.
Pacific Paradise = 198 deluxe stateroomsCaribbean Paradise = 214 deluxe stateroomsMediterranean Paradise = 764 deluxe stateroomsAs a check,
198+214+764 = 1176 total rooms
The answer is confirmed.
Is the relationship linear, exponential, or neither? X/-12 -6 0 6 y/9 12 20 40
Answers
Answer: The relationship between the variables x and y in the given data points is linear.
Step-by-step explanation: A linear relationship is one in which the change in the y-value (output) is always the same for a given change in the x-value (input), regardless of the starting point. In other words, the slope of the line is constant.
In this case, the slope of the line can be calculated by finding the difference in y-values for a given difference in x-values between two points. We can pick any two points, for example:
(X: -6, Y: 12) and (X: 6, Y: 20)
The slope can be calculated by:
m = (20 - 12) / (6 - (-6)) = 8/12 = 2/3
This means that for every 1 unit increase in x, y increases by 2/3 units.
This is a linear relationship.
In contrast, in an exponential relationship, the y-value increases (or decreases) at a constantly increasing (or decreasing) rate as the x-value increases.
Venus has an angular diameter of about 0.018° when it is a distance of about 38.5 million km from Earth.
What is its true diameter (physical size)? Round to the nearest hundred km.
Answers
The true diameter of the Venus given the angular diameter of 0.018 is about 39.7 million km.
What is angular diameter?An angular distance used to describe how big a sphere or circle seems from a certain point of view is known as the angular diameter, angular size, apparent diameter, or apparent size. It is known as the visual angle in the vision sciences and as the angular aperture in optics (of a lens). The angular diameter may also be thought of as the angle that a camera or eye must spin around in order to view from one side of an apparent circle to the other.
Given that the angular diameter of Venus is 0.018 degrees.
The true diameter of the planet is calculate using the following formula:
diameter = distance (angular diameter / 57.3)
Substitute the value of distance = 38.5 million and angular diameter = 0.018 degrees.
diameter = 38.5 * 10^6 (0.018 / 57. 3)
diameter = 39. 7 million
Hence, the true diameter of the Venus given the angular diameter of 0.018 is about 39.7 million km.

If a/2-b/3 = 1 what is 2a+3b in terms of b
Answers
If a/2-b/3 = 1, then we can write:
2(a/2-b/3) = 2
Combining like terms, we have:
a - b/3 = 1
Multiply both sides by 3 to get:
3a - b = 3
Now, we can add b to both sides of the equation:
3a = b + 3
Finally, we can divide both sides by 3 to get:
a = (b + 3)/3
Now we can substitute this value of a into the original equation
2a + 3b = 2(b + 3)/3 + 3b = 2b/3 + 6/3 + 3b = 2b + 2 + 3b = 5b + 2
So 2a+3b = 5b + 2 in terms of b
