Step-by-step explanation:
The smaller triangle and the bigger triangle have the same angle of 60 on one side.
They also have a common point at the top, which is also called a common angle.
You only need two angles to show that two triangles are similar, because the other angle has to be the same because all angles in a triangle add up to 180.

Answer:
Z is 66. If you want an explanation, I could give it to you, FYI.
Answer:
x=66°
Step-by-step explanation:
Solve for x:
If the two vertical lines are parallel, then the given angles are same side interior angles that are supplementary angles. This means that their values add up to 180°:
∠1+∠2=180°
Substitute known values:
[tex]x+114=180[/tex]
Subtract 114 from both sides to isolate x:
[tex]x+114-114=180-114\\\\x=66[/tex]
The value of x is 66°.

(HELP PLEASE!! answer all the questions) Mr. Smith decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the center, there is a window that is 5 34feet long.
Each president's picture is 6 inches wide.
If the pictures are placed side by side on either side of the window, how many pictures can he fit on this wall?
Answer the questions to solve this problem.
1. How many feet long is the space Mr. Thuman wants to fill with pictures? Explain how you know.
Write your answer in the space below.
2. Convert this length to inches. (There are 12 inches in 1 foot)
Write your answer in the space below.
3. How many pictures will Mr. Thuman use? Explain how you found your answer.

Answer:
4.00 feet48 inches8 pictures4 picturesStep-by-step explanation:
1. The available wall space is the difference between the length of the wall and the length of the window:
9.75 ft - 5.75 ft = 4.00 feet
__
2. At 12 inches per foot, this is ...
(4 ft)(12 in/ft) = 48 in
__
3. If the pictures are 6 inches wide, Mr. Smith can use ...
(48 in)/(6 in/picture) = 8 pictures
__
4. If the pictures are 10 inches wide, Mr. Smith can use ...
(48 in)/(10 in/picture) = 4.8 pictures
There is room for 4 pictures. Space for a fraction of a picture is not useful. This number is even, so 4/2 = 2 pictures can be placed on either side of the window.

Which option correctly shows how this formula can be rearranged to isolate x^2?
Options in picture.
Answers
Answer:
A
Step-by-step explanation:
We have:
[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]
And we want to isolate x₂.
So, let’s first remove the denominator by multiplying both sides by it:
[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]
The right side will cancel. This will leave:
[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]
Now, we can subtract x₁ from both sides. So:
[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]
Finally, we will multiply both sides by -1. So:
[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]
Hence, our answer is A.

Step-by-step explanation:

Solve.
9.46 = y
Answer:
9.5
Step-by-step explanation:
y is the adjacent side of the given 38 degree angle. You are given the hypotenuse of right angle triangle. So the trig function that you need to use is the Cosine
Cos(38) = y / 12
multiply both sides by 12
12*cos(38) = 12*y/12
12*cos(38) = y
12*0.7880= y
y =9.456

Step-by-step explanation:
since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.
Now you can just do 2.5+5=7.5 so DC=7.5
