Answer:
Supplementary Angles
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 .
3a3=180°3 a=60°
