Given that

- A40
- B100
- C80
- D50

### Example

Given that

### Solution

The measure of an inscribed angle of a circle is half the measure of the central angle subtended by the same arc. This means that the measure of

Since the measure of a central angle is equal to the measure of the arc that subtends it, the measure of arc

The measure of
