Know the Answer?

Chloe Pratt · Answer 1

Let the measure of one of the supplementary angles be a.

Measure of the other angle is 2 times a

Emilie Benitez · Answer 2

Let the measure of one of the supplementary angles be a

.

Measure of the other angle is 2 times a

.

So, measure of the other angle is 2a.

If the sum of the measures of two angles is 180°, then the angles are supplementary.

So, a+2a=180°

3a=180°

To isolate a, divide both sides of the equation by 3.
