3. A ship leaves port and travels 49 miles at a standard position angle of 30°. The ship then travels for 89 miles in a standard position angle of 70°. At that point, the ship drops anchor. A helicopter, beginning from the same port, needs to join the ship as quickly as possible. Tell the helicopter's pilot how to get to the ship. 4. A plane is traveling at 400 mph along a path 40° North of East. A strong wind begins to blow at 50 mph from North to South. If no adjustment is made for the wind, what are the resulting bearing and grounds peed of the plane? (Hint: North to South means the angle would be -90" or 270.)
