Any of the hands on the dial can rotate 360 degrees.
Move the hour hand to the position at seven o’clock zero minutes:
360: 12 * 7 = 210.
Move the minute hand twenty minutes: (360: 12) * (60:20) = 120.
However, the hour hand moves slightly when the minute hand is rotated: (360: 12) * (60:20) = 10.
As a result, the angle between the arrows is: 210-120 + 10 = 100 degrees.
