Question

write the algebraic expression described. recall that two angles are complementary if their sum is 90°. if one angle measures y°, express the measure of its complement in terms of y°. the measure of its complement in terms of y° is ()°.

Explanation:

Step1: Recall complement definition

Let the measure of the complement be $x$. We know that $y + x=90$.

Step2: Solve for $x$

Subtract $y$ from both sides of the equation: $x = 90 - y$.

Answer:

$90 - y$
