You can put this solution on YOUR website! Assume you mean:
find the angle between the clock hands at 9:47
:
Find the Angles in relation to 12 being 360 degrees
Large hand: 47/60 * 360 = 282 degrees
Small hand: 270 + 47/60 * 30 = 293.5 degrees (one hr is 30 degrees)
:
293.5 - 282 = 11.5 degrees is the angle between the hands
