Question

If two angles are complementary and one of those angles of those angles is twice the measure of the other then what is the supplement of the smallest angle

Answer 1

150°

Explanation:

If x represents the measure of the smaller angle, then ...

x + 2x = 90° . . . . . the angle and twice the angle are complementary

x = 90°/3 = 30° . . . divide by the coefficient of x

The angle that is supplementary to 30° is ...

180° -30° = 150°
