Physics Problem Help Please?

Fairgoers ride a Ferris wheel with a radius of 4.50 m, the bottom of which is 1.75 m from the ground. The wheel completes one revolution every 32.0 s. A penger drops his keys when he is three quarters of the way up and at an angle of 45� to the vertical. Where do the keys land relative to the base of the ride? (Take the positive direction to be to the right.)
