Choose and apply the correct circle-angle theorem for a secant and a tangent meet outside with intercepted arcs 160 and 60 degrees.
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Classify the angle by vertex position and rays or chords.
2. Select the matching circle-angle relationship.
3. Compute the requested measure.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Applying a memorized half rule without checking the diagram type.
