Question

the measure of an angle is 17°. what is the measure of its complementary angle?

Explanation:

Step1: Recall complementary - angle definition

Complementary angles add up to 90°. Let the given angle be \(A = 17^{\circ}\) and its complementary angle be \(B\). Then \(A + B=90^{\circ}\).

Step2: Solve for the complementary angle

We can find \(B\) by subtracting \(A\) from 90°. So \(B = 90^{\circ}-17^{\circ}\).
\(B = 73^{\circ}\)

Answer:

73
