Question

look at this diagram: if $overleftrightarrow{hj}$ and $overleftrightarrow{km}$ are parallel lines and $mangle kli = 49^{circ}$, what is $mangle mln$?

Explanation:

Step1: Identify vertical - angle relationship

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

Step2: Apply vertical - angle property

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

Answer:

$49$
