Question

The supplement of an angle exceed it by 60^o, then the measure of the angle is

• A. 180^o
• B. 120^o
• C. 60^o
• D. 90^o

Answer 1

The correct option is C

60^o

Let the measure of the angle be x

Thus, it's suppliment = 180 - x

Accordingly,

180 - x - x = 60

180 - 2x = 60

-2x = 60 - 180

-2x = -120

Thus, x = 60^o
