Question

su and vx are parallel lines. which angles are vertical angles? ∠utw and ∠utr ∠utw and ∠xwy ∠utw and ∠str ∠utw and ∠xwt

Explanation:

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent. In the given diagram, the lines $RY$ and $SU$ intersect at point $T$, and the lines $RY$ and $VX$ intersect at point $W$. $\angle UTW$ and $\angle XWY$ are formed by the intersection of the same two - intersecting lines ($RY$ and the pair of parallel lines which can be considered in terms of intersection at the transversal - like situation), and they are opposite each other.

Answer:

$\angle UTW$ and $\angle XWY$
