Larry Yu · Answer 1

Two angles are supplementary when they add up to 180 degrees ⇒

d = 180 - c

and

d = 8c (given)

8c = 180 - с

8 с + с = 180

9 с = 180

с = 180/9

m∠с = 20°

m∠d = 8c = 8*20 = 160°

Angle c and angle d are supplementary, the measure of angle d is eight times the measure of anglec. find measure of angle c and measure of angle d
