The vertex of an angle is the common endpoint of the two rays that form the angle.

Step2: Identify the common endpoint in the given angle

In the given angle, the two rays are the horizontal ray (with a point \(Y\) on it) and the vertical ray (with a point \(W\) on it). The common endpoint of these two rays is the point \(X\).

Answer:

\(X\)
