Yeah pretty sure I was over-thinking this. I was trying to use tan^2𝜃 = sin^2𝜃/cos^2𝜃 and this just confused me with the ^2 and I was getting weird fractions. Basically I was trying to use the method I used for cos𝜃 but this is how I ended up solving it:

tan𝜃 = sin𝜃/cos𝜃
tan𝜃 = -3/5 / 4/5
tan𝜃 = -3/5 * 5/4
tan𝜃 = -15/20
tan𝜃 = -3/4

Thanks for your explanations + diagrams rushy and dynamo, appreciate it.
