From a stationary 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 traveled 20 meters since she knows how far she is
from the target. If the bull’s eye is 4 meters wide, how far did the first
arrow travel? You may assume that the arrows traveled in straight-line
paths and that the bull’s eye is circular. Round answer to the nearest tenth.
