Question

find the requested angle... complement of 54°
a 108 degrees
b 306 degrees
c 126 degrees
d 36 degrees

Explanation:

Step1: Recall complement - angle formula

Complementary angles add up to 90°. Let the angle be $x$. If one angle is 54°, then $x + 54^{\circ}=90^{\circ}$.

Step2: Solve for the unknown angle

$x=90^{\circ}- 54^{\circ}$.
$x = 36^{\circ}$.

Answer:

D. 36 degrees
