Question

look at this diagram: if gj and jl are parallel lines and m∠jkh = 54°, what is m∠ihk?

Explanation:

Step1: Identify angle - relationship

$\angle{JKH}$ and $\angle{IHK}$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. So $m\angle{IHK}=m\angle{JKH}$.

Answer:

$54$
