Question

Refer to the figure to complete the following activity. If measurement of BOC=30, then what does the measurement of arc CAB=?

Answer 1

Major arc CAB has measure 330 because ...

Answer 2

... if m<BOC = 30, then measure of minor arc BC alsoo = 30. (Recall the the measure of a central angle is the same as its intercepted arc.) Then, measure of major arc BOC = 360 - 30 = 330.
