Question

look at this diagram: if $overleftrightarrow{eg}$ and $overleftrightarrow{hj}$ are parallel lines and $mangle hif = 50.3^{circ}$, what is $mangle gfi$?

Explanation:

Step1: Identify angle - relationship

$\angle HIF$ and $\angle GFI$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent, so $m\angle GFI=m\angle HIF$.

Answer:

$50.3$
