Question

The measure of an angle that is 18 o less than its complement is a. 54 o b. 64 o c. 36 o d. 38 o

Answer 1

Let us assume 'x' is an angle and 'x-18' is its complement
So, x + x -18 = 90

2x = 90 + 18

2x = 108

x = 108/2

=> x = 54 degrees

Verification: we know that 54 degrees + 36 degrees = 90 degrees
                      now, 54 - 36 = 18

Therefore, the required angle is 36 degrees - because they have asked for an angle that is 18 degrees LESS than its complement

Hope this helps amigo
