Question

Circle C has center at the origin and radius 9. Another circle, K, has a diameter with one end at the origin and its opposite end at the point (x,y)=(0,14). These circles intersect at two points. Let P be the first quadrant point which is on both C and K

Find polar coordinates (r,θ) for point P chosen so that r is positive and 0≤θ≤π/2.
