Question

If the measure of an angle is 13º, find the measure of its supplement.

Answer 1

167

Explanation:

Supplementary angles add to 180

x+13 = 180

Subtract 13 from each side

x = 180-13

x =167

The supplement to 13 is 167

Answer 2

167°

Explanation:

The supplement of an angle will always be the measure of an angle, when added to the original, will equal 180°.

If we know the measure of 1 of these angles, we can easily find the measure of the other, assuming x is the missing angle measure.

`13+x=180`

We can subtract 13 from both sides to get the value of x.

`13+x-13=180-13\\\\x=167`

Hope this helped!
