Given (2/3,sqr5/3), compute

Hi! I have a quick question. I know how to solve it for sin and cos, but I'm having trouble with tan. I know that it would be y over x and you have to solve, but I don't know how. Any tips or help?

Ky,
 
You said you know how to solve it for sinθ and cosθ.  Recall that
 
tanθ = sinθ / cosθ.
