A town clock has "hands" that are of length 62cm and 85cm.
Find the angle between the hands at half past ten.
I'm confused because I've only been given two sides ?
Well, since "angle between the hands" is obviously the angle made by the
hands at the center of the clock, then at 10.30 the hour-hand points halfway
between 10 and 11, and the minute-hand points at 6, so angle = 135 degrees;
you don't even need the given lengths...
