Question

In circle O, central angle COD has a measure of 48. Find the measure of arc BC. In your final answer, include all your work ​

Answer 1

Measure of arc BC = 132°

Explanation:

Measure of the central angle COD = 48°

Therefore, measure of arc AB = 48°

Since, segment AC is a diameter and central angle for a diameter is 180°.

Measure of major arc ABC = 180°

measure of arc AB + measure of arc BC = 180°

48° + measure of arc BC = 180°

Measure of arc BC = 180° - 48°

= 132°
