The measure of an angle which is 20 more than its complement is A) 35 B) 100
C) 55 D) 80

The correct answer is c. 55

C=complement; A=the angle=C+20 degrees
C+A=90 degrees Substitute for A
C+C+20degrees=90 degrees Subtract 20 degrees from each side.

2C=70 degrees Divide each side by 2.
C=35 degrees ANSWER 1:The complement measures 35 degrees.

A=C+20 degrees=35 degrees + 20degrees=55 degrees ANSWER 2:The measure of the angle is 55 degrees
