Question

the measure of an angle is 70°. what is the measure of its complementary angle?

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles add up to \(90^{\circ}\). Let the unknown angle be \(x\).

Step2: Set up the equation

We know that \(x + 70^{\circ}=90^{\circ}\).

Step3: Solve for \(x\)

Subtract \(70^{\circ}\) from both sides of the equation: \(x=90^{\circ}-70^{\circ}\).

Answer:

\(20\)
