Question

If BAC = 320°, what is the measure of BC?

a. 40°
b. 80°
C. 160°
d. 320°

it also asks for the measure of angle BMC using the same photo!

Answer 1

BC = 40º

BMC = 40º

Step-by-step explanation: Since the measure the major and minor arcs add up to 360º, just subtract 320 from 360 to find BC which is 40º. <BMC is also 40º because the measure of the arc is equal to its corresponding angle.
