Question

find the measure of the missing angle

Explanation:

Step1: Recall angle - sum property

The sum of adjacent angles forming a straight - line is 180°.

Step2: Calculate the missing angle

Let the missing angle be $x$. We have $x + 148^{\circ}=180^{\circ}$. Then $x=180^{\circ}-148^{\circ}$.
$x = 32^{\circ}$

Answer:

$32^{\circ}$
