Ответ:
For the angle, notice how it wants it relative to due east - as we have a triangle we can use to work out internal angles with trig, here I would find it easiest to find the boat's initial angle in terms of due west, then take that away from 180 to find the larger angle! I don't have a calculator with trig buttons on with me, but if you type the tan sum into a scientific calculator to find the west angle, then subtract that from 180 you'll have your answer.
