Question

two angles are such that one of the angle is for backside of supplement then the angle is dash and a supplement is dash​

Answer 1

Answer:

Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle.

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°

Answer 2

Answer:

Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle.

Supplementary Angles

Let the measure of one of the supplementary angles be

a .Measure of the other angle is 2 times a .Sum, 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°
