Question

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

Explanation:

Step1: Set up the equation

Let the measure of the complement be \(x\). Since the sum of complementary angles is \(90^{\circ}\), we have \(d + x=90\).

Step2: Solve for \(x\)

Subtract \(d\) from both sides of the equation: \(x = 90 - d\).

Answer:

\((90 - d)\)
