an airplane flies between two points on the ground that a re 500km apart. the destination is directly north of the origination. The plane flies with an air speed of 120 m/s. if a constant wind blows at 10.0 m/s. due west during the flight, what direction must the plane fly relative to the north to arrive at the destination.

make answer clear

i cant figure out these two parts

A pilot wants to fly north. The plane has an airspeed of 350 km/h. There is a 50 km/h windblowing to the west.a. What direction does the plane need tohead? [E82°N]b. What is the plane’s velocity relative tothe ground? [346 km/h [N]]
