yep and then you do the sqrt( -29.9^2 +98.2^2) to get the velocity
The velocity of an airplane with respect to the ground is 200 m/s at an angle of 30 degrees NORTH of EAST. The velocity of the airplane with respect to the air is 150 m/s at an angle of 60 degrees NORTH of EAST. What is the velocity of the air with respect to the ground?
