Answer 2

Answer:

At 7'o clock, the minute hand is at 12 and the hour hand is at 7 i.e. the minute hand is 210 degrees behind the hour hand (going clockwise). In 20 minutes (i.e. at 7:20), it makes up 330*20/60 = 110 degrees

Angle between the hour and minute hand at 3:30

a circle is 360 degrees. 360/12 = 30 degrees per hour.
