Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. State the known theorem or construction being used.
2. Connect arcs, radii, or auxiliary angles to the target relationship.
3. Conclude the desired angle relationship.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
