Question

look at this diagram: if $overleftrightarrow{hj}$ and $overleftrightarrow{km}$ are parallel lines and $mangle mli = 131^{circ}$, what is $mangle kln$?

Explanation:

Step1: Identify angle - relationship

$\angle MLI$ and $\angle KLN$ are vertical angles.

Step2: Apply vertical - angle property

Vertical angles are congruent. So $m\angle KLN=m\angle MLI$.

Answer:

$131$
