Question

Circle O is shown. Line segments B O and O C are radii. Point A is on the circle and is not within angle B O C.
The measure of Arc B A C is 240. What is the ratio of the measure of the major arc to the measure of the minor arc?

3:1
1:3
2:1
1:2

Answer 1

Arc BAC measures 240°, so the other arc BC measures 360° − 240° = 120°. The ratio major:minor = 240:120 = 2:1.
