Question

the measure of an angle is 18.1°. what is the measure of its complementary angle?

Explanation:

Step1: Recall complementary angle formula

Complementary angles sum to \(90^\circ\). Let the complementary angle be \(x\), so \(18.1^\circ + x = 90^\circ\).

Step2: Solve for \(x\)

Subtract \(18.1^\circ\) from both sides: \(x = 90^\circ - 18.1^\circ\).
Calculate: \(x = 71.9^\circ\).

Answer:

\(71.9^\circ\)
