15
35
39
45

Answer 1

Would you say that m6 and m7 are congruent? Or complementary? Or supplementary?

Answer 2

If they are congruent, set them equal to each other:

4x-15 = x+30

If they are supplementary:

4x-15 + x+ 30 = 180

Or if they are complementary

4x-15 + x+30 = 90

Answer 3

Hint: Angles that form Z's are congruent.
