Question

question 10(multiple choice worth 5 points) (14.03 lc) what is the measure of the unknown angle? n 132° 48° 49° 51° 53°

Explanation:

Step1: Recall angle - sum property

The sum of adjacent angles on a straight - line is 180°.
Let the unknown angle be \(n\). So \(n + 132^{\circ}=180^{\circ}\).

Step2: Solve for \(n\)

Subtract 132° from both sides of the equation: \(n=180^{\circ}-132^{\circ}\).
\(n = 48^{\circ}\)

Answer:

A. 48°
