Analyze the angle formed by two tangents from an external point when the intercepted arcs are 310 degrees and 50 degrees.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the two intercepted arcs made by the tangent points.
2. Subtract the minor arc from the major arc.
3. Divide by 2, or use 180 degrees minus the minor arc.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using half the sum of arcs.
