Question

the measure of an angle is 39.6°. what is the measure of its supplementary angle? blank° submit

Explanation:

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\). Let the angle be \(x = 39.6^\circ\), and its supplement be \(y\). So, \(x + y=180^\circ\).

Step2: Solve for the supplementary angle

Rearrange the formula: \(y = 180^\circ - x\). Substitute \(x = 39.6^\circ\): \(y=180 - 39.6 = 140.4\).

Answer:

\(140.4\)
