Relative motion question

[F.B]

I really need help with these questions they are too hard.

Anyways the question is:

A helicopter travels with an air speed of 55 m/s. The helicopter heads in the direction [35 degrees N of W]. What is velocity relative to the ground if the wind velocity is (a) 21 m/s [E] and (b) 21 m/s [22 degrees W of N]?

I need to converst the speeds to velocity but i dont have time to convert them to displacements. So can anyone please help me?

I figure it should take you about 10 minutes if you do it by hand, 5 if you use a calculator. Since that amount of time has already passed, it's clear that it is too late for me to help you!
