Answer: A. 40 and 40

Since the two angles you’re solving for are supplementary, their sum equals 180.

The equation would be:
3x-5+2x-15=180
Add like terms:
5x-20=180
+20 +20
——————-
5x=200
X=40

Check with the original equations:
3x-5
3(40)-5
120-5
115

2x-15
2(40)-15
80-15
65

Add:
115+65= 180

So the answer is correct. ;)
