Question

if (overleftrightarrow{tv}) and (overleftrightarrow{wy}) are parallel lines and (mangle vus = 125^{circ}), what is (mangle tux)?

Explanation:

Step1: Identify angle - relationship

$\angle VUS$ and $\angle TUX$ are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. So $m\angle TUX=m\angle VUS$.

Answer:

$125^{\circ}$
