Hey there! :D
When you are finding the area of corresponding sides, you square the number of the ratio of the similar lengths.
The screens a little blurry, but I'm assuming the corresponding side is represented as:
![\frac{a}{b}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bb%7D%20)
So, you would keep a and b where they are, (you would be confusing the areas if you switched it in any way) and then just square the variables.
"C" is the best answer. I hope this helps!

If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22
71
175
180
Are the correct answers I just took the test/
Answer:
its 2/6ths its only multiplied by 2
Step-by-step explanation:
Answer:
Supplementary angles add to 180 degrees.
Angles of a triangle add to 180 degrees.
So, the angles of this triangle are 2x, 3x, and 70.
This means we can have the equation: 5x+70=180, and 5x=110, meaning that x=22
Let me know if this helps!
