I am trying to solve some equations for example: tanθ = 2/4 or tan15 = x/30 but I do not know how I would use a Calculator to solve these as I do not know how to format them or which symbols to use for θ and x, thanks.

A TI-84 Plus cannot symbolically solve any equation, but there are two other options to solve equations:
Algebraically on paper, and then use the calculator to get a decimal estimate.
Graph both sides of your equation, and determine the intersection point(s). This will result in the solutions as well.
