Question

Two angles are supplementary. The measure of one angle is x and the measure of the other angle is 4x, find the value of xa. 36b.18c.4d.5

Answer 1

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

so

In this problem

x+4x=180

solve for x

5x=180

x=36

therefore

the answer is the option A
