Question

HOW TO CALCULATE THE SUPPLEMANTRY ANGLES? ​

Answer 1

Step-by-step explanation:

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°
