Question

the measure of an angle is 57°. what is the measure of its complementary angle?

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles add up to 90°.

Step2: Set up the equation

Let the complementary - angle be \(x\). We have \(x + 57^{\circ}=90^{\circ}\).

Step3: Solve for \(x\)

\(x=90^{\circ}-57^{\circ}\)

Answer:

\(33^{\circ}\)
