Maths Trigonometry Question?

Maths Trigonometry Question?



I really need help with this question as it's my final maths trig question, but I just can't seem to understand how to figure it out at all... it's really quite frustrating. I would really appreciate it if someone could please answer the question for me. I know SOH CAH TOA can't be used because we're not dealing with right triangles, but I don't know whether to use the Sine Law or the Cosine Law and how to use either to find the length of BD to two decimal places. Please help, anyone!
