Question

the pair of a supplementary angle is : 52 :108 , 42:138 , 82 :10​

Answer 1

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°

Step-by-step explanation:

Answer 2

Sum of supplementary angles is 180°.

OUT of these pairs only in pair 2 the sum of angles is 180°....

So, pair (42:138) are supplementary angles.
