your answer to the nearest tenth of a mile.
Three boats are at sea: Jenny one (J1), Jenny two (J2), and Jenny three (J3). The crew of
J1 can see both J2 and J3. The angle between the line of sight to J2 and the line of sight to
J3 is 45 degrees. If the distance between J1 and J2 is 2 miles and the distance between J1
and J3 is 4 miles, what is the distance between J2 and J3?
