Question

Circle o is shown below the diagram is not drawn to scale if m

Answer 1

∠ O = 72°

Explanation:

the inscribed angle R is half the measure of its intercepted arc NQ , then

arc NQ = 2 × 36° = 72°

the central angle O is equal to the measure of the arc that subtends it , so

∠ O = arc NQ = 72°
