Question

how would I do this?
If two angles are supplementary and one of them is 30°, what is the measurement of the second angle?

Answer 1

I think its 150 im not sure!!

Answer 2

you are right because the sum of supplementary angles is 180 degrees so if one is 30 the other is 150

Answer 3

if 2angles, a and b, are supplementary; then a+b = 180

Answer 4

thank u I just wanted to make sure
