Question

the measure of an angle is 2°. what is the measure of its supplementary angle?
□°
submit

Explanation:

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\).

Step2: Calculate supplementary angle

Let the angle be \(2^\circ\). Let its supplement be \(x\). Then \(x + 2^\circ= 180^\circ\). Solving for \(x\), we get \(x = 180^\circ - 2^\circ = 178^\circ\).

Answer:

\(178\)
