Explanation:

Step1: Recall angle - naming convention

An angle is named with the vertex letter in the middle. The 20 - degree angle has vertex \(V\), and the rays forming the angle are \(VE\) and \(VT\).

Step2: Identify the correct angle name

Based on the naming rule, the angle can be named \(\angle EVT\).

Answer:

\(\angle EVT\)
