Question

look at this diagram: if $overleftrightarrow{tv}$ and $overleftrightarrow{wy}$ are parallel lines and $mangle vux = 60^{circ}$, what is $mangle yxz$?

Explanation:

Step1: Identify vertical - angle relationship

$\angle VUX$ and $\angle YXZ$ are vertical angles.

Step2: Apply vertical - angle property

Vertical angles are congruent. So $m\angle YXZ=m\angle VUX$.

Answer:

$60$
