No problemo dude. So what do you know about sin θ·cot θ? Well, cot θ = cosθ/sinθ. Hence, the sin θ cancels out and what do you know? You are solving for cos θ. Now, you know that the quadrant is II (2). Hence, cos is also negative. So, tan θ = opp/adj = -(5/12). So, cos θ = adj/hyp which is just -12/13.
