An angle has a measure of n degrees. Which of the following expressions would be used to find the measure of its complement?

A.n-90
B.90-n
C.180-n
D.n-180

1 answer

The complement of an angle is found by subtracting the angle's measure from 90 degrees. Therefore, to find the measure of the complement of an angle measuring \( n \) degrees, the correct expression would be:

B. \( 90 - n \)
