1. A boat race runs along a triangular course marked by buoysA,B, andC. The race starts with the boats headed west for3900meters. The other two sides of the course lie to the north of the first side, and their lengths are1600meters and2800meters. Draw a figure that gives a visual representation of the situation, and find the bearings for the last two legs of the race. (Round your answer to one decimal place.)
2. A plane flies 810 miles from Franklin to Centerville with a bearing of 75°. Then it flies 647 miles from Centerville to Rosemount with a bearing of 32°. Draw a figure that visually represents the situation, and find the straight-line distance and bearing from Franklin to Rosemount. (Round your answers to one decimal place.)
3. Two ships leave a port at 9 a.m. One travels at a bearing of N 53° W at 12 miles per hour, and the other travels at a bearing of S 67° W at 19 miles per hour. Approximate how far apart they are at noon that day. (Round your answer to one decimal place.)
