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?

Yes x = 2/3 and y = sqrt(5)/3 and T is the angle

By pythagorean, the hypotneuse is 1

sin T is sqrt(5)/3

cos T is 2/3

tan T = y/x = sqrt(5)/2 = sin T / cos T
