Question

What is the measure of the supplementary angle of the 65˚ angle?

A.50˚
B.40˚
C.130˚
D.310˚

Answer 1

None of them

Explanation:

Supplementary angles have 180 degrees

50+65=115

40+65=105

130+65=185

310+65=375

Answer 2

115

Explanation:

When two angles are supplementary, their measures must add up to 180 degrees. Therefore, if we call the other angle x:

x+65=180

x=180-65=115 degrees
