A carpenter is building four picture frames in the shape of right triangles. He calculates the lengths of the longest side of each triangle, in inches. Which list of lengths is in order from shortest to longest?
Answer:
Step-by-step explanation:
This problem requires the use of the Pythagorean Theorem to find the lengths of the sides of a piece of property in the shape of a right triangle
Example:
Taylor finds a piece of property in the shape of a right triangle. She finds that the longer leg is 10 m shorter than twice the length of the shorter leg and the hypotenuse is 20 m longer than the longer leg. Find the lengths of the sides of the triangular lot.

Answer:
117
Step-by-step explanation:
it makes alternate exterior with the 177 angle
Answer:
117°
Step-by-step explanation:
y° = 180° - 48° - 44°
y° = 88°
since opposite angles are equal,
2z° + 2y° = 360°
2z + (2*88)° = 360°
2z° = 360°-176°
2z° = 184°
z° = 92°
Now, check the picture attached.
44° + a° + 87° = 180°
a = 49°
Now, a° + b° + z ° = 180°
b° = 180° - 49° - 92°
b = 39°
a quadrilateral has four angles that sums up to 360°
thus,
117° + (39° + 48°) + (44° + 49°) + (c° + 39°) = 360°
c° + 39° = 63°
c° = 24°
Finally,
c° + b° + x° = 180°
x° = 180° - 24° - 39°
x° = 117°

i need the equation you solved it with too.
Answer:
[tex]\huge\boxed{x=59}[/tex]
[tex]\texttt{Read the explanation for the equation.}[/tex]
Step-by-step explanation:
Given that lines [tex]l[/tex] and [tex]m[/tex] are parallel, that means that we can establish some basic angle relationships here.
Since both lines are cut by a transversal, that means all angles formed by that line will be equivalent.
[tex](3x-33)\textdegree[/tex] and [tex](2x+26)\textdegree[/tex] are going to be equivalent because they are alternate exterior angles. These are formed by two parallel lines being cut by a transversal, and they will always be equal.
Since we know that both angles are equivalent to each other, we can set the expressions equal to each other to find x.
[tex](3x-33) = (2x+26)[/tex]
Here's your equation, by the way.
We can now solve for x.
[tex]3x-33=2x+26[/tex]
Add 33 to both sides:
[tex]3x=2x+59[/tex]
Subtract 2x from both sides:
[tex]x=59[/tex]
Therefore, x = 59.
Hope this helped!

You are a woodworker who is designing a custom doghouse.
The customer has chosen a different siding for the back of the house
The base of the triangle measures 3 feet, 2 inches, and the height is 4 feet.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Here,
Height of doghouse = 4 feet = 4 * 12 = 48 inches
Base of doghouse = 4 feet 2 inches = 36 * 12 + 2 = 38 inches
Area of the triangle = 1 / 2 * base * height
Area of the triangle = 1 / 2 * 48 * 38
Area of the triangle = 912 square inches
Thus, the required area of the back of the doghouse is 912 square inches.

The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the
kitchen, playroom, and dining room are in the ratio 4: 3:2. The combined area of these
three rooms is 189 square feet. What is the area of each room?
Answer:
kitchen:84 square feet
playroom: 63 square feet
dining room:42 square feet
Step-by-step explanation
total ratio =9
therefore 1 portion=189/9
=21
therefore area of;
kitchen;21*4= 84 square feet
play room;21*3 = 63 square feet
dining room;21*2 = 42 square feet
The areas of each room are 84, 63, and 42 square feet.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, the ratio of the three areas is 4 : 3 : 2.
The sum of the ratios is:
4 + 3 + 2
= 9
Since the total area is 189, it follows:
9 = 189
1 = 21
Therefore, the value of 1 is 21.
Since the value of 1 is 21, the value of 4 is:
4 ×21 = 84
Similarly, the value of 3 and 2 are:
3 ×21 = 63
2 × 21 = 42
Hence, the areas of each room are 84, 63, and 42 square feet.

The limit does not exist.
Answer: lim x--> 0 f(x) does not exist.

We need to evaluate both the right and left hand limits in this problem.
lim as x--> 0 from the left = 5(0) - 8 = 0 - 8 = -8
lim as x--> 0 from the right = |-4-(0)| = |-4| = 4

Henry can paint a room in 5 hours and nick can do it in 2 hours. How long will it take Henry and nick to paint the room together?
Answer:
1 3/7hours
Step-by-step explanation:
If Henry can paint a room in 5 hours, then he must be able to paint 1/5 of the room in 1hour
If nick can do it in 2 hours, he must be able to paint 1/2 of the room in 1 hour
Together they can paint (1/5+1/2) of the room in 1 hour
1/5+1/2 = (2+5)/10
= 7/10
This means that they can both paint 7/10 of the room in 1hour
Hence the can use 10/7 hours to paint 1room
Time taken for them to paint the room together is 10/7 hrs = 1 3/7hr

The sketch shows the distance three runners travel during a race. Describe what occurs at times A,B,C and D. In what order do the runners finish. Explain.
Answer:
Notice that the distance is in the y-axis, and the time in the x-axis.
First, let's see what happens in the four points:
A) You can see that in point A, the steepness of the line increases, this means that the speed of the runner increases in that point.
B) In this point, the runner that increased his/her speed in point A crosses the graph of another runner, this means that they are at the same distance to the end and at the same time.
C) In this point again two runners are at the same distance and the same time, and we also can see that the runer that increased his/her speed at point A, now has reached the end of the race (because his line stops increasing, wich means that he/she already finished the race)
D) The las runner finishes the race at point D.
Then the first runner that finishes the race is the one with the shorter graph (shorter graph means that he ran for less time than the others, wich means that he/she finished first)
The last runner is the one that finished at point D,
The middle one finishes right after the point C.
Determine what the solution is to the following system? Y=3/4x-1 & y=4/3x-1
Answer:
(0, -1)
Step-by-step explanation:
There are multiple ways of solving this however- since both equations are already in Y-Intercept form, we will use the "Equal Values Method"
First, since both equations are equal to Y, we can set them equal to each other and solve for X
[tex] \frac{3 }{4} x - 1 = \frac{4}{3} x - 1[/tex]
To start, you must eliminate the fraction using a "fraction buster" multiply EVERYTHING by 4 then simplify.
[tex]3x - 4 = 5 \frac{1}{3}x - 4[/tex]
Since we still have a fraction, we shall do it one more time. This time we multiply by 3
[tex]9x - 12 = 6 x - 12[/tex]
Now, solve how you normally would.
9x = 6x
-6x
3x = 0
X = 0
Now, since we know what X would equal in the solution, we are able to plug in X as 0 in one of our equations. We can choose the first one!
[tex]y = \frac{3}{4} (0) - 1[/tex]
Now solve which would lead to y = -1
You have your solution as
(X,Y)
(0,-1)
