Question

Supplementary angles add up to

Answer 1

Two supplementary angles add up to exactly 180 degrees.

If two angles don't add up to exactly 180 degrees, or if it takes more
than two to do it, then none of those angles are supplementary.

Answer 2

The answer is:

180°

Work/explanation:

The sum of supplementary angles is
`\sf{180^o}`. So that means that if we know one angle, we can set up an equation, where the right side is equal to 180, and find the measure of the other angle by solving the equation in terms of the variable.
