Determine the measure of the unknown angle or arc. Show your work.

Answer 1

28.

Arc BC = 107 degrees

---Since the given angle is on the center of the circle, the arc has the same measure.

Angle BAC = 53.5 degrees

---Since this is an inscribed angle, the measure of the angle is half of the corresponding arc.

29.

Arc BC = 92 degrees

---Since we are given an inscribed angle, the corresponding arc is double the measure of the angle.

Hope this helps!
