question find the measure of the missing angle. answer attempt 1 out of 2 a =

Explanation:

Step1: Recall angle - sum property

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

Step2: Set up the equation

Let the given angle be 110° and the missing angle be (a). Then (a + 110^{\circ}=180^{\circ}).

Step3: Solve for (a)

Subtract 110° from both sides of the equation: (a=180^{\circ}-110^{\circ}).

Answer:

70°
