An airplane flies at airspeed (relative to the

Question

air) of 250 km/h . The pilot wishes to fly due
North (relative to the ground) but there is a
65 km/h wind blowing Southwest (direction
225◦
).

plane (measured clockwise from North)?
Answer in units of ◦

Answer 1

You are given to vectors of the triangle
Resultant=wind+heading
heading=resulting-wind
break up resultant, and wind, into N, and E components, subtract, and you then have the components of heading. You can figure heading by theta=arctan(East/North).
