angle between the minute hand and the hour hand of a clock when the time is 8.30 is 75 degrees.

at 8:30 hours hand is sharply at the center of 8 and 9. minutes hand is sharply at 6 the angle between 6 and 9 is 90 degree from 6 to 9 dividing for every 0.5 having 15 degrees each so angle is 5*15 =75 degree or 90-15=75degree

75º

Angle traced by hour hand in 17/2 hrs = (360/12 x 17/2)º = 255.

Angle traced by min. hand in 30 min. = (360/60 x 30 )º = 180.

Required angle = (255 - 180)º = 75º.

If we measure the angle between the minute hand and the hour hand in the clockwise direction, Then the answer is: 360 -75 = 285 degrees
