From a fixed point directly in front of the center of a bull's eye, Kim aims two arrows at the bull's eye. The first arrow nicks one point on the edge of the bull's eye; the second strikes the center of the bull's eye. Kim knows the second arrow goes 20 meters since she knows how far she is from the target. If the bull's eye is 4 meters wide from second arrow, how far did the ?rst arrow goes? You can consider that the arrows traveled in straight-line paths and that the bull's eye is circular.
