clock is a circle - so 360 degrees- there are 12 divisions- so each division is 30 degrees.. big hand is at 4 ... small hand is between 7 and 8 ..... 4-5-6-7 ninety degrees.
1hr - 30 deg
1 min- 1/2 deg
20 min - 10 deg
so totally - 100 deg Got that..........

To be precise, as the little hand will also have moved, the answer would not be 240° for the large angle and 120° for the small angle, as some might say. The little hand will have moved 20°, so the answer would be that the large angle would be 220° and the small angle would be 140°.
On a non-military clock (civil, 12-hour) . . .-- The hour-hand is moving 360 degrees in 12 hours = 30 degrees per hour.3:20 is 31/3 hours past noon, so the hour-hand has moved 10/3 x 30 = 100 degrees.-- The minute-hand is moving 360 degrees per hour. So it starts at zero at thebeginning of each hour, and after 1/3 of the hour, it has moved 360/3 = 120 degrees.-- The angle between them at 3:20 is [ 120 - 100 ] = 20 degrees.
Each minute on the clock is 1/60 of the 360 degree circle or 6 degrees. There are 20 minute lines between 12 and 4 therefore, 20 times 6 is 120 degrees.
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
