Question

name the marked angle in 2 different ways.

Explanation:

1. An angle can be named by its vertex alone if no other angles share that vertex. Here, the marked angle's vertex is $W$, so one name is $\angle W$.
2. An angle can also be named using three points: the two endpoints of its sides and the vertex (with the vertex in the middle). For this angle, the sides are $\overline{XW}$ and $\overline{VW}$, so the name is $\angle XWV$.

Answer:

$\angle W$, $\angle XWV$
