Question

look at this diagram: if ce and fh are parallel lines and m∠cdb = 67°, what is m∠edg?

Explanation:

Step1: Identify vertical - angle relationship

$\angle CDB$ and $\angle EDG$ are vertical angles.

Step2: Apply vertical - angle property

Vertical angles are congruent. So, $m\angle EDG=m\angle CDB$.

Answer:

$67$
