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

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).
