Question

ZABC and ZQRS are supplementary angles.

If the measure of ZABC = 175°, what is the
measure of ZQRS?
mZQRS = [?]

Answer 1

<QRS=5°

Answer:

<ABC+<QRS=180

175+<QRS=180

<QRS=180-175=5

Answer 2

Supplementary angles are any two angles that add up to 180 degrees. If angle ABC equals 175 degrees, then angle QRS should equal 5 degrees. I hope this helps.
