Help with High School Maths hard question 1 Attachment(s) Please help! 
Do you know the cosine rule and the sine rule? 
1 Attachment(s) Attachment 10008 The diagram above gives the angles, so you just need to show the remaining lengths are correct. 
How did you find that you should use those angles and triangles? 
Quote:

Well you can use them to find all lengths and angles in the figue. I'd start with the cosine rule on the triangle with sides $\sqrt3$ and $1$. 
I have done everything that I can I have done law of cosines and law of sines but I really can't find the answer could you please tell me the answer to the question. 
What did you get?

Archie TOLD you how. Added hint: after doing what Archie suggested, you'll have the hypotenuse's length; next calculate the missing leg's length (should get ~1.93164), next calculate the right triangle's angles... It is not easy to help you: your damn diagram is not labelled:ninja:
