Ответ:
Degree measure of arc AB = 120°
Length of arc = 41.9 in.
Step-by-step explanation:
✔️Measure of Central angle is the same as Measure of the intercepted arc
Therefore,
Degree measure of arc AB = 120°
✔️Length of arc =
r = 20 in.
Length of arc =
= 41.887902
Length of arc = 41.9 in. (Nearest tenth)
