Question

An angle measures 126.6° more than the measure of a supplementary angle. what is the measure of each angle

Answer 1

Let the measure of the angle be x, then the measure of the second angle is 180 - x.

Then, x - 126.6 = 180 - x
=> 2x = 180 + 126.6 = 306.6
=> x = 306.6 / 2 = 153.3

Thus the first andle is 153.3 and the second angle is 26.7.
