Let x = the angle

180 - x = its supplement since supplementary angles add up to 180 degrees.

180 - x = 1/2 x

2(180 - x) = 2(1/2) x

360 - 2x = x

360 = 3x

120 = x

The angle is 120 degrees, and its supplement is 60 degrees.

Answer 2

Answer:

Half of the right angle is 90/2 = 45°

Supplementary angle is equal to 180°.

Thus, the supplementary angle of 45° will 180-45 = 135°

135° is the answer.
