A circle C has center at the origin and radius 7. Another circle K has a diameter with one end at the origin and the other end at the point (0,10). The circles C and K intersect in two points. Let P be the point of intersection of C and K which lies in the first quadrant. Let (r, θ) be the polar coordinates of P, chosen so that is positive and 0 <= θ <= 2. Find r and θ.
