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:
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.
