Question

the measure of an angle is 12°. what is the measure of its complementary angle?

Explanation:

Step1: Recall complementary - angle definition

Complementary angles add up to 90°.

Step2: Set up the equation

Let the complementary angle be \(x\). Then \(x + 12^{\circ}=90^{\circ}\).

Step3: Solve for \(x\)

\(x=90^{\circ}- 12^{\circ}=78^{\circ}\)

Answer:

\(78^{\circ}\)
