3. A
hiking party is lost in a national park. Two ranger stations have received an
emergency SOS signal from the party. Station B is 75 miles due east of station
A. The bearing from station A to the signal is S E and the bearing from station
B to the signal is S W.

(a) Draw a diagram that gives a
visual representation of the problem.

(b) Find the distance from each
station to the SOS signal.

(c) A rescue party is in the park
20 miles from station A at a bearing of S E. Find the distance and the bearing
the rescue party must travel to reach the lost hiking party.
