Answer/Step-by-step explanation:
If two triangles are similar, their corresponding angles would be of equal measure of degree.
8. The 3rd angle of the smaller ∆ is x = 76°, while that of the larger ∆ is y = 44°. As we can see, the corresponding angles of both ∆s are not congruent or equal to each other. Therefore they ARE NOT SIMILAR.
9. x = 43°, while y = 106°.
Both triangles have corresponding angles that are congruent to each other.
Therefore, both triangles ARE SIMILAR.
![\frac{11-x}{3x+2} =\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B11-x%7D%7B3x%2B2%7D%20%3D%5Cfrac%7B1%7D%7B2%7D%20%20)
Cross multiply
2(11-x) = 1(3x+2)
Distribute
22-2x = 3x+2
Subtract 22 from both sides
-2x = 3x-20
Subtract 3x from both sides
-5x = -20
Divide both sides by -5
x=4
