Question

Find the supplement of a 55° angle, in degrees.

Answer 1

125°

Explanation:

Supplementary angles add up to 180°, so the supplement of 55° and 55° should add up to 180°.

Lets say x is the supplement of 55°.

180° = 55° + x°

-55° both sides

125° = x°

x° = 125°

The supplement of 55° is 125°.

Answer 2
