To angles are supplementary. the first angle measures 60. what is the measurement of the second angle?

Question

A. 30

B. 90

C. 120

D. 180

Answer 1

c 120

Answer 2

if 2 angles are supplementary, then their sum is 180 degrees

so have x be the measure of the second angle and the measure of the first one

then,

x+y=180

x+60=180

x=180-60=120

then the answer is c

Answer 3

c120  supplementary meansthe sum of the two angles need to add to 180 - therefore the second one is 180 - 60
