Asked by Debby
The pilot of an airplane wishes to fly due north, but there is a 71 km/h wind blowing toward the east.
(a) In what direction should the pilot head her plane if its speed relative to the air is 314 km/h?
° west of north
Should the angle just be the opposite of the one created by the east wind? I'm not sure how to "undo" it

Vp + Vw = 314i
Vp + 71 = 314i
Vp = -71 + 314i
Tan Ar = 314/-71 = -4.42254
Ar = -77.26o = Reference angle.
A = -77.26 + 180 = 102.74o CCW = 12.74o
