Question

If two angles are supplementary, and the angle measurements are in the ratio 3:1, what is the measure of the smaller angle?

Answer 1

the answer to this is 40=

Explanation:

I did this

Answer 2

The measure of smaller angle = 45°

Explanation:

Finding the unknown angle

Ratio of the supplementary angles = 3 :1

The angles are 3x , x

Supplementary angles add up to 180°

3x + x = 180

4x = 180

x = 180 ÷ 4

x = 45°

3x = 3*45 = 135°
