Question

what is the measure of the missing angle?

Explanation:

Step1: Use the property of complementary angles

Complementary angles sum to \(90^{\circ}\). Let the missing angle be \(x\). We know that \(x + 20^{\circ}=90^{\circ}\).

Step2: Solve for \(x\)

Subtract \(20^{\circ}\) from both sides of the equation: \(x=90^{\circ}- 20^{\circ}\).

Answer:

\(70^{\circ}\)
