Supplementary angles add to equal 180 degrees. If two angles are supplements of each other and one of the angles measures 62 degrees, you can set its sum with the unknown angle, x, equal to 180 and solve for the unknown angle x.
Equation:
180 = x + 62
Subtract 62 from both sides:
118 = x
Answer:
The measure of the other angle is 118°.
