4. Navigation a) A sailboat is 7 miles offshore directly east of Marina A. Marina B is directly north of Marina A at an angle of 30° north of west from the boat. Sketch a diagram of the boat and the two marinas. How far must the sailboat sail to reach Marina B? b) Suppose we cut the angle in a) in half and put Marina B directly north of Marina A at an angle of 15° north of west from the boat. How far must the boat sail to reach Marina B? Is the distance half, or less than half, or more than half what it was in a)?
