Step-by-step explanation:

The data points go from 16 to 28 so the ends need to  bet there

The median is the middle line in the box

There are 12 data points, so the middle is between the 6th and 7th point

(21+23)/2 = 22

A has a median at 21  and B has a median at 23

C has a median at 22

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
