Answer: 75 degree

Step-by-step explanation:

At 8 ' o' clock

The angle between 'Hour hand and Minute hand' is 240 degree

[each dial = 30 degree, at '8' its 30*8 = 240]

Now in 1 minute hour hand moves : 1/2 degree

                           minute hand moves : 6 degree

So in 30 minutes:

Hour hand moves : 30/2 = 15 minutes

Minute hand moves: 6*30 = 180 degree

Minute hand % 180 degree position. Hour hand at 240+15=255 degree position.

Angle between them = 255-180 = 75 degree

ALTERNATE:

Angle = 11/2 * M - 30*H     [M- corresponding minute, H-corresponding hr]

          = 11/2 * 30 - 30* 8

         = 11*15 - 240 = 165 - 240 = 75 degree (- sign is neglected)
