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

On a digital 12 hour clock system it is shown as 07:20On a digital 24 hour clock system it is shown as 19:20
180o
The clock on the back shows that the time is 2:20
5:20
In regular time, you should say 3:20am and 3:20pm

"20 past 5" means that it is 5:20 on the clock. In this case, the minute hand is pointing at the 4th minute mark (20 minutes past the hour), while the hour hand is pointing directly at the 5. This is a common way to express time in everyday conversation.

I can only understand that you are asking what 820 means in time. 8:20 is 8:20 am, so this is 20 minutes past 8 o clock in the morning.
The angle of reflection is equal to the angle of incidence, so if the angle of incidence is 20 degrees, then the angle of reflection will also be 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.
