**MathMate**, Friday, August 31, 2012 at 3:19pmTrouble-free way to get resultant:

resolve into x- and y-components and add.

Wind is FROM N45W, which means that its direction is S45E.

Take East = x, and North = y,

the wind vector is then

<40sin(45),40cos(45)>

The velocity vector of the plane is

<200sin(60),200cos(60)>

The combined vector (resultant) is therefore

<40sin(45)+200sin(60), 40cos(45)+200cos(60)>

Find the magnitude and direction of the resultant in the usual way.
