Draw and label a diagram - vectors tail to tip
(ground speed)2 = 4002 + 402 - (2)(400)(40) cos 45°
Use ground speed with Law of Sines to determine angle of direction.
An airplane is heading north at an airspeed of 700 km/hr, but there is a wind blowing from the northwest at 40 km/hr.
The plane will end up flying= degrees off course
The plane's speed relative to the ground will be= km/hr
