Question

look at this diagram: if $overrightarrow{eg}$ and $overrightarrow{hj}$ are parallel lines and $mangle gfi = 69.1^{circ}$, what is $mangle hif$?

Explanation:

Step1: Identify angle - relationship

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

Step2: Apply parallel - lines property

When two parallel lines are cut by a transversal, corresponding angles are congruent. So $m\angle HIF=m\angle GFI$.

Answer:

$69.1$
