Find the angle formed by intersecting chords inside a circle when the intercepted arcs measure 90 degrees and 50 degrees.
Using a hint is okay. It just tells the trainer to give you a little more review.

use half the sum of intercepted arcs.
Hidden until you reveal it.
Chords must intersect inside the circle; use half the sum of the intercepted arcs.
Enter your answer
Your answer is equivalent to the expected form.

1. Identify the two arcs intercepted by the vertical angle pair.
2. Add the two arc measures.
3. Divide the sum by 2.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using half the difference, which applies to exterior angles.
