Question

If ∠A and ∠B are supplementary angels and ∠A is two times as large as ∠B, find the measures of ∠A and ∠B.

The measure of ∠B is ___

The measure ∠A is ____

Answer 1

Angle B = 60 / Angle A = 120

Answer 2

Explanation:

Let x = angle B

2x = angle A

Supplementary = 180

X + 2X = 180

3X =180

X = 60

Angle B = 60

Angle A = 2(60) = 120
