What reason can you give for the fact that if two angles are congruent then their
measures are equal?
(I think it’s a type of postulate)
Answers
Answer:
Explained below
Step-by-step explanation:
If two angles are congruent, it means that they have the same angle whether in degrees or radians.
Now, angles are said to be congruent so as long as the measure of the angles are the same and regardless of them point in the same or different directions.
They must not necessarily be made with lines having the same length.
For example, in the diagram of the 2 triangles I've attached, angle C and Z are congruent, and they are both marked accordingly by one short curved line. Similarly angle A and B are congruent and they are both marked accordingly by two short lines.

What is a percentage increase?The percentage increase formula is the ratio of value increased to the original value and multiplied by 100.
We have,
Ricardo:
At 9 years old = 56 inches tall
At 12 years old = 62 inches tall
The percentage increase is given by:
= (62 - 56) / 56 x 100
= (6 / 56) x 100
= (3 / 28) x 100
= 300 / 28
= 10.7142 %
Rounding to its nearest tenth we get,
= 10.7 %
Thus the percentage increase in Ricardo's height is 10.7%.

Find the cos sin and tan of 28 degrees in terms of the variables x, y, and k.
Answers
Answer:
[tex]sin(28) = \frac{y}{k} , cos(28) = \frac{x}{k} , tan(28) = \frac{y}{x}[/tex]
Step-by-step explanation:
For this problem, k is the hypotenuse, x is the side adjacent to 28, and y is the side opposite 28.
I would remember SOH CAH TOA.
S - Sine
O - Opposite
H - Hypotenuse
For this, it shows that the sine of the angle is opposite over hypotenuse. Therefore, y/k.
C - Cosine
A - Adjacent
H - Hypotenuse
For this, it shows that the cosine of the angle is adjacent over hypotenuse. Therefore, x/k
T - Tangent
O - Opposite
A - Adjacent
For this, it shows that the tangent of the angle is opposite over adjacent. Therefore, y/x

Given that the radius of the circle is
2 yd.
Answers
Step-by-step explanation:
Area of first triangle = 1/2bh
the base of the triangle = the radius of the semi-circle = 2yd
height = 5yd
Area = 1/2(5yd)(2yd)
A = 5yd(yd)
A = 5y^2d^2 squared units.
since the second triangle also has the same dimensions as the first triangle
hence:
Area of the second triangle = 5y^2d^2 squared units.
Area of semi-circle = πr^2
Area = π(2yd)^2
A = 4πy^2d^2 squared units

In an effort to reduce accidents, the highway authority decided to reduce the speed limit on a road from 65 mi/h to 50 mi/h. To travel 650 miles, how many more hours will it take a car averaging 50 mi/h than a car averaging 65 mi/h?
Answers
Answer:
The answer is 3 hours
Step-by-step explanation:
The reason being, 65 mi/h can be divided by 650 to equal 10, so it would take 10 hours to get through those 650 miles with your car that drives 65 mi/h
Then we can do the same things with 50, that equals 13. So 13 - 10 = 3. It took the 50 mi/h car 3 more hours to get through 650 miles than the 65 mi/h car!

Answers
Answer:
first I started 300 girls were asked and out of 300 only 12 girls like bowling as fav sport. so I divided 12 into 300 so my answer is 36%
300÷12= 36%
Answer:
4%
Step-by-step explanation:
1. Convert the problem to an equation using the percentage formula: P% * X = Y.
2. P is 10%, X is 150, so the equation is 10% * 150 = Y.
3. Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

What are the possible values of the missing term in the geometric sequence?
4, _, 9, ...
Answers
==========================================================
Explanation:
r = common ratio
To get any term in a geometric sequence, we multiply the previous term by r.
So that means 4r is the second term, since 4 is the first term.
The third term is (4r)*r = 4r^2, which is equal to 9 as given to us.
4r^2 = 9
4r^2 - 9 = 0
(2r)^2 - (3)^2 = 0
(2r - 3)(2r + 3) = 0 ... difference of squares rule
2r-3 = 0 or 2r+3 = 0
2r = 3 or 2r = -3
r = 3/2 or r = -3/2
r = 1.5 or r = -1.5
We can use each r value to find the possible second term
S = 4r = 4*(1.5) = 6
S = 4r = 4*(-1.5) = -6
The second term is either 6 or -6.
We could have this sequence: 4, 6, 9, ...
Or we could have this sequence: 4, -6, 9, ...
The possible values of the missing term in the geometric sequence should be considered as the 6 or -6.
Calculation of the missing values:Since
r = common ratio
For get any term in a geometric sequence, we have to multiply the previous term by r.
Here first term is 4 so the second term be 4r
And, the third term be [tex](4r)*r = 4r^2[/tex] , that is equivalent to 9
[tex]4r^2 = 9\\\\4r^2 - 9 = 0\\\\(2r)^2 - (3)^2 = 0[/tex]
(2r - 3)(2r + 3) = 0
2r-3 = 0
or
2r+3 = 0
2r = 3 or 2r = -3
[tex]r = 3/2\ or\ r = -3/2[/tex]
r = 1.5 or r = -1.5
Now
S = 4r = 4(1.5) = 6
S = 4r = 4(-1.5) = -6
Hence, The possible values of the missing term in the geometric sequence should be considered as the 6 or -6.
