Question

the measure of the missing angle

Explanation:

Step1: Recall angle - sum property

The two angles are adjacent and form a straight - line. The sum of angles on a straight - line is 180°.
Let the missing angle be \(a\). One angle is 48°. So, \(a + 48^{\circ}=180^{\circ}\).

Step2: Solve for the missing angle

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

Answer:

132°
