Question

look at this diagram: if $overleftrightarrow{hj}$ and $overleftrightarrow{km}$ are parallel lines and $mangle jil = 62.3^{circ}$, what is $mangle kln$?

Explanation:

Step1: Identify angle - type relationship

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

Step2: Recall vertical - angle property

Vertical angles are congruent, so $m\angle KLN=m\angle JIL$.

Answer:

$62.3$
