What are you thinking so far? Have you drawn a diagram?
Interestingly, you don't need sine or cosine rule to work this out.
If you want to use trig:
You can find the vertical height of the parallelogram as you are given the length and the area.
You are already given the hypotenuse of the triangle.
Sine or cosine is probably easier though.
