Question #6484

The measure of an angle is half of its supplement. Find the measure of the angle.

Expert's answer

Two angles are supplementary if they add up to 180 degrees. Let's denotate unknown angle by x. Then we can construct the following equation:

x=1/2*(180-x) because supplementary angle for x is 180-x

hence 2x=180-x

3x=180

x=60^{o} - answer

x=1/2*(180-x) because supplementary angle for x is 180-x

hence 2x=180-x

3x=180

x=60
