Question

The measure of an angle is 167°. What is the measure of its supplementary angle?

Answer 1

13

Explanation:

If two angles are supplementary, this means that they total 180 degrees.

Since the measure of one angle is 167, this means that the measure of the other angle is:

`180-167=13`

So, the other angle measures 13 degrees.

And we're done!

Answer 2

x=13

Explanation:

Supplementary angles add to 180 degrees

x+167 = 180

Subtract 167 from each side

x+167-167= 180-167

x = 13
