Question

look at this diagram: if (overleftrightarrow{jl}) and (overleftrightarrow{mo}) are parallel lines and (mangle mnp = 127^{circ}), what is (mangle onk)?

Explanation:

Step1: Identify vertical - angle relationship

$\angle MNP$ and $\angle ONK$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. So $m\angle ONK=m\angle MNP$.

Answer:

$127$
