Question

select the correct choice that completes the sentence below. the measure of an angle that is its own complement is 90, 360, 180, 45 (options in a dropdown).

Explanation:

Step1: Recall complement definition

Complementary angles sum to \(90^\circ\). Let the angle be \(x\). If it's its own complement, then \(x + x = 90^\circ\).

Step2: Solve the equation

Simplify \(2x = 90^\circ\), so \(x=\frac{90^\circ}{2}=45^\circ\).

Answer:

45
