the formule for finding the angle between hour hand minute hand is (11 M)/2- 30h.

or 30h - (11m)/2. because any angle made twice in an hour

so the answer is exactly 75 degrees.

hour hand takes 155 degree at8:30

the minute hand takes 180 degree after the 30 minutes

so that the angle difference between hour and minute hand is 175 degree.

Angle made by hour hand and minute hand assuming to point towards 2 consecutive digits in a clock is 30 degre... Consider time : '8:30' .......................there fore angle between digits 8 and 6 is 2x30=60 degree... .......................and half of an hour moves hour hand half the way to next digit.... that means creating an angle 30/2= 15 degree......So.... Final answer is 60+15=75 degree.....:-)

convert the gn time into hrs 8.30 i.e (510/60) or (17/2)hrs...we noe dat in 12 hrs the angle made by hour hand is 360deg...therefore ,say A= [(17/2)*(360/12)]deg or 255 deg  ....also noe dat minute hand make 360 deg in 60 min...therefore, say B= [30*360/60] deg or 180 deg .....the difference between A nd B gives u the angle between hour hand nd minute hand i.e 255 deg - 180 deg=75 deg.
