Question

The measure of angle D is 5 times the measure of angle E. The two angles are supplementary. Find the measure of each angle

Answer 1

Angle e = x        angle d = 5x    supplementary means they add up to 180
x + 5x =180
6x = 180
6x/6 = 180/6
x = 30
so angle e = 30 and angle d = 5(30) = 150
