Question

4 multiple choice 1 point what is the measure of ∠abd? 74° 23° 113° 180°

Explanation:

Step1: Recall linear - angle property

The sum of angles on a straight - line is 180°. So, $\angle ABC = 180^{\circ}$.

Step2: Find $\angle ABD$

We know that $\angle ABC=\angle ABD + \angle DBC$. Given $\angle DBC = 67^{\circ}$, then $\angle ABD=180^{\circ}-\angle DBC$.
$\angle ABD = 180^{\circ}- 67^{\circ}=113^{\circ}$

Answer:

$113^{\circ}$
