What is the missing exterior angle?

A. 39
B. 83
C. 97
D. 180

B

Step-by-step explanation:

The exterior angle is the sum of the two given angles. (The are called the remote interior angles. The are not connected to the exterior angle we are supposed to find.)

exterior angle = 44 + 39

exterior angle = 83

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the answer for this question is 38
