Question

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

Explanation:

Step1: Recall angle - sum property of a straight - line

The sum of angles on a straight - line is $180^{\circ}$.

Step2: Set up the equation

Let the missing angle be $a$. We have $a + 110^{\circ}=180^{\circ}$.

Step3: Solve for $a$

$a=180^{\circ}- 110^{\circ}=70^{\circ}$.

Answer:

$70^{\circ}$
