Question

look at this diagram: if $overleftrightarrow{su}$ and $overleftrightarrow{vx}$ are parallel lines and $mangle vwt = 125^{circ}$, what is $mangle xwy$?

Explanation:

Step1: Identify angle - type relationship

$\angle VWT$ and $\angle XWY$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. So $m\angle XWY=m\angle VWT$.

Answer:

$125$
