2. 6.6 Applying Trig Functions • A boat travels at 35 mph for 2 hr on a course 53° east of north; then it changes to a course 143° east of north and travels for another 3 hrs. Determine the distance from the boat to its home port. What is the bearing from the boat’s home port to its location at the end of 5 hr?
