Simple form.
For 12 hours we take 360 degree.
And 8-2 = 6.
So, 360/12*6 = 180.
For 12 hours we take 360 degree.
And 8-2 = 6.
So, 360/12*6 = 180.

Simple formula :- 1/2(60x-11y).
Here x=hour.
y=minute.
Put any value in time then got answer in degree.
And solve many other questions.

y=minute.

AS the question say time is 8am-2pm.
Time between 8am-2pm is 6 hours gap.
Now, we have 12 hours. Which is 12=360deg.(the clock rotates).
After that we take 6 hours and total degree(360)of 12 hours.
Which looks like this:
360/12*6=180deg.
Time between 8am-2pm is 6 hours gap.
Now, we have 12 hours. Which is 12=360deg.(the clock rotates).
After that we take 6 hours and total degree(360)of 12 hours.
Which looks like this:
360/12*6=180deg.

For a 1 hour the angle is 360/12=30.
The distance between 8 and 2 is 6.
So for 6 hours the angle will be as 6*30=180.
The distance between 8 and 2 is 6.
So for 6 hours the angle will be as 6*30=180.

Is it true in every case (2:13) ?

@Sarang !
If angle between minutes hand and Hour hand will be asked.
i.e.
Angle between Hour hand and minute hand at the time 2:13. etc.
If angle between minutes hand and Hour hand will be asked.
i.e.
Angle between Hour hand and minute hand at the time 2:13. etc.

Angle = 60*h/2.
Where, h=hour.
Where, h=hour.

360°/12 = 30°.
8 to 2 o'clock = 6 hrs.
30° * 6 = 180°.
8 to 2 o'clock = 6 hrs.
30° * 6 = 180°.

Simple method :
Total hours between 8 am to 2pm (H) = 6 hours (normal counting)
minutes (M)=0.
Use this formula {angle= [30*H - (11/2)*M] }.
Where H= hours, M= minutes. Put the values
Angle = 30*6 - (11/2)*0.
= 180-0 = 180 degrees.
P.S. If minutes are given put that value in same formula.
Total hours between 8 am to 2pm (H) = 6 hours (normal counting)
minutes (M)=0.
Use this formula {angle= [30*H - (11/2)*M] }.
Where H= hours, M= minutes. Put the values
Angle = 30*6 - (11/2)*0.
= 180-0 = 180 degrees.
P.S. If minutes are given put that value in same formula.
