Answer

a.$102^{\circ}$ b.$9^{\circ}$

Work Step by Step

a. The two angles are supplementary, so they add to 180 degrees. Therefore, to find the measure of angle x, $180-78=102^{\circ}$ a. The two angles are complementary, so they add to 90 degrees. Therefore, to find the measure of angle y, $90-81=9^{\circ}$
