Question

Angle x is conplementary to angle Y. Angle X is supplementry to angle Z. the measure of Angle Z is 102°.

what is the measure of angle Y? explain how you found ur answer

Answer 1

y = 12

First, I remembered that complementary angles are angles that add together to get 90 and supplementary angles are angles that add together to get 180. Next I subtracted 102 from 180 and got 78, which means that x = 78. Then I subtracted 78 (x) from 90 and got 12 (y).
