The wind seems quite steady, and first blows him due east for 15 km, and then 1I km in a direction 7.5 degrees north of east @25% Part (a) How far east, in kilometers, has the wind blown Jack? @25% Part (b) How far north, in kilometers, has Jack been blow.n? 25% Part (c) Confident that he will eventually find himself in Spain, Jack falls asleep. When he wakes up, he notices the wind is blowing him gently 1I degrees south of east but after traveling for 29 km, he finds himself back on the island where he started! How far, in kilometers did the wind blow him while he was sleeping? 25% Part (d) Assuming the wind blew the same direction all night, what direction, in degrees north of west, did the wind blow Jack during the night?

To calculate angle, use the below formula,
Theta = tan-1(y component/ x component)
This will give you direction in degrees north of west.
X and y components were used to calculate resultant in part (c)
