The RPM has nothing to do with the length of the belt.
My simplistic guess would be that since the saw's circumference is twice the motor's, it will be turning half as fast. So 850 RPM.
As for the angle X, of course it depends on the belt length. If the two circles are infinitely far apart, the angle will be zero since the belt will be flattened. If they are touching, the angle will be 180.
I've forgotten way too much of the trig I never knew to actually put it down in a formula, though.
