Question

Two angle are supplementary . If one of the angle is double then other in angle . Find the two angle

Answer 1

Answer:

If the measure of the angle is twice the measure of the other, find the measure of each angle. ... If the sum of the measures of two angles is 180° , then the angles are supplementary.

Answer 2

Answer:

Two angles are supplementary. If the measure of the angle is twice the measure of the other,

find the measure of each angle.

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°

Simplify.3a=180°

To isolate a , divide both sides of the equation by 3 .3a3=180°3    a=60°

The measure of the second angle is,2a=2×60°       =120°

So, the measures of the two supplementary angles are 60° and 120° ....
