C because there is 180 degrees in a triangle. 147+17=164 and 180-164 is 16
Answer:
<h2>28%</h2>
Step-by-step explanation:
![0.28=\frac{28}{100}](https://tex.z-dn.net/?f=0.28%3D%5Cfrac%7B28%7D%7B100%7D)
then
$0.28 is 28% of a dollar.
Answer:
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
Step-by-step explanation:
Both angles are the same because of similar angles being the two horizontal lines are parallel. All we have to do is solve the equation when we make the angles equal to each other. Follow the steps below.
![9x + 7 = 10x \\ 7 = x \\ x = 7](https://tex.z-dn.net/?f=9x%20%2B%207%20%3D%2010x%20%5C%5C%20%207%20%3D%20x%20%5C%5C%20x%20%3D%207)

Answer:
The length of rectangle is 16 meters and the width of rectangle is 7 meters
Step-by-step explanation:
Let
L -----> the length of the rectangle
W ---> the width of the rectangle
we know that
The perimeter of rectangle is equal to
----> the perimeter of a rectangle is twice the sum of its length and its width
we have
![P=46\ m](https://tex.z-dn.net/?f=P%3D46%5C%20m)
so
![46=2(L+W)](https://tex.z-dn.net/?f=46%3D2%28L%2BW%29)
simplify
-----> equation A
----> equation B
substitute equation B in equation A and solve for W
![23=(2W+2+W)](https://tex.z-dn.net/?f=23%3D%282W%2B2%2BW%29)
![23=3W+2](https://tex.z-dn.net/?f=23%3D3W%2B2)
![3W=23-2](https://tex.z-dn.net/?f=3W%3D23-2)
![3W=21](https://tex.z-dn.net/?f=3W%3D21)
![W=7\ m](https://tex.z-dn.net/?f=W%3D7%5C%20m)
Find the value of L
therefore
The length of rectangle is 16 meters and the width of rectangle is 7 meters
