The angles are 30 and 150.
Work Step by Step
Let n represent the first angle. The other is five times as large, which means the other angle is 5n. The sum of two supplementary angles is 180, so we obtain: n + 5n = 180 6n = 180 Divide both sides by 6: n = 30 Since n = 30, 5n = 150. The angles are 30 and 150.
