Captain Jack Sparrow has been marooned on an island in the Atlantic by his crew, and decides to build a raft to escape. The wind seems quite steady, and first blows him due east for 19 km, and then 7.5 km in a direction 9.5 degrees north of east. 1) How far east, in kilometers, has the wind blown Jack? dE = 2) How far north, in kilometers, has Jack been blown? dN = 3) Confident that he will eventually find himself in Spain, Jack falls asleep. When he wakes up, he notices the wind is blowing him gently 11degrees south of east - but after traveling for 22 km, he finds himself back on the island where he started! How far, in kilometers, did the wind blow him while he was sleeping? |r| =

dN =
3) Confident that he will eventually find himself in Spain, Jack falls asleep. When he wakes up, he notices the wind is blowing him gently 11degrees south of east - but after traveling for 22 km, he finds himself back on the island where he started! How far, in kilometers, did the wind blow him while he was sleeping?
