angle = arc/radius
10/17
=0.58...radians

The circumference of your circle is 34pi
So the fraction of the circle that this arc takes up is 10/(34pi)
The fraction of your circle that the angle takes up is (theta)/(2pi)
These fractions should be the same, so solve
10/(34pi) = (theta)/(2pi)
hope this helps!
