In what direction should the pilot head the plane (measured clockwise from North)?

Answer in units of degrees.

**Steve**, Monday, December 31, 2012 at 12:05am43/√2 = 30.4, so the wind's vector is (-30.4,-30.4)

If the plane flies on heading θ,

(-30.4,-30.4)+(430cos(θ-45°),430sin(θ-45°)) = (0,y)

so, we have -30.4 + 430cos(θ-45) = 0

cos(θ-45) = 30.4/430 = 4.05

so, the plane flies N41°E
