An airplane is heading due south at a speed of 734 km/h . A wind begins blowing from the southwest at a speed of 110 km/h (average).
In what direction should the pilot aim the plane so that it will fly due south?

The heading of wind from southwest is
northeast which is 45o N. of E.

Vaw = Va + Vw = -734i.
Va + 110[45o] = -734i.
Va + 110*Cos45 + i110*sin45 = -734i.
Va + 77.8 + 77.8i = -734i.
Va = -77.8 - 811.8i, Q3.

Tan A = -811.8/-77.8. = 10.43445.
A = 84.5o S. of W. = 5.5o W. of S. =
The direction.
