Trigonometry help?

1.what si the velocity of the glider (vp) relative tot he air in terms of i and j

2. Express the velocity of the wind (vw) in terms of i and j

3. Express the velocity of the slider (vt) in terms of i and j and find the true speed of the plane.

( I dont to much want jsut the answers but a clear explanation of how to get the answer)
Thank you.
Update: I put slider and meant glider in question 3
