How would i find the velocity of the ship relative to earth?

[ryan578]

Homework Statement

A ship sets sail from Rotterdam, The Netherlands,
heading due north at 7.00 m/s relative to the water. The local
ocean current is 1.50 m/s in a direction 40.0º north of east.
What is the velocity of the ship relative to the Earth?

Homework Equations

Vr=Vs-Vc r=relative s=ship c=ocean current

The Attempt at a Solution

I tried using the equation above but i noticed i needed to get a direction and that is where i am stuck.
