Question

look at this diagram: if $overleftrightarrow{hj}$ and $overleftrightarrow{km}$ are parallel lines and $mangle jil = 41^{circ}$, what is $mangle mln$?

Explanation:

Step1: Identify vertical - angle relationship

$\angle JIL$ and $\angle MLN$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. So $m\angle MLN=m\angle JIL$.

Answer:

$41$
