GOT IT!!!
n = 542
w = 490

I took the obtuse triangle and cut it in two making it easier to use the SIN laws to figure out the length of hypotinuse of the rt angled triangle then continued to use the SIN law and BAMMO!!!

wow, i was CLOSE but glad you figured it out on your own too! :) what made things easier for me is Sin (90) = 1 so i used that to get my W and N i must have rounded too much on my 489, i was ONE off.

one thing... If the guy didnt want 6 significant figures, he shouldnt have posted the length as 284.065 :P i would have rounded it to three if the length he posted was three :) Oh well, Math semantics really. Let me know if you have/find any other math problems, i really like them :)

Yes i used Sin 90 =1 too....t'was a good refresher course...now I have the co-ordinates to find 3 caches and at each are more numbers for the 4th cache lol

Hope I can get out there soon.
