Factor the numerator to get:
(-3z(z+5))/(z+5) now you notice that (x+5) cancel out leaving:
-3z
7, is the part of the solution set because of the number it has inside of it. 8 years old worth of
Angles 1 and 2 are vertical angles which makes # 3 angle 1 = angle 2
Because angle 1 and 2 are vertical angles, then A and E would be similar due to the vertical angle theorem as well.
The answer would be D.
The correct answer would be C
