Question

The measure of an angle is 119.4°. What is the measure of its supplementary angle?

Answer 1

60.6°

Explanation:

Supplementary angles equal 180 degrees. So we can show this with the following equation:

119.4 + x = 180

where x is the measure of the other supplementary angle.

If we subtract 119.4 from both sides, we get the the value of x, which is 60.6.

Answer 2

180 - 119.4 = 60.6

So the answer is 60.6
