Yeah sorry the whole chapter is on sines and cosines and special triangles, so they insist on making life harder. haha..they gaave the answer as 12 sqrt 6

That's all i don't understand - Feb 24th 2008, 02:38 AMmr fantastic

it would be good if you told us your difficulty. if you have trouble setting up the sine, cosine and tangent trig ratios, say so, and we can address it. if your problem was the algebra, then Mr. Fantastic already addressed that. do you understand the problem now? or is there something else?
