? = 210*sin(70°) + 150*sin(70°+(130°-180°)) + 125*sin(70°+(130°-180°)+(120°-180°))

False answer, the heck. XD. Never Mind, problem isn't meant for anyone except the elite.

sine - a/sina = b/sinb = c/sinc then the inverse for angles.
I'm a fucking brainlet too though.

that last angle is 50 degrees not 40

in pic where i say 'angle between f and CD'
should be 'angle between e and CD' sorry, but you get what you pay for :D

here is the solution

>>8680896
solution yes, but the thought process behind it?

The solution to the assignment you guys proposed, 168(.29) , was correct. Thank You!

heres a hint

>>8679747
calling it an assignment doesn't mean it's not homework

>>8679857
That solution is correct, you are just a retard.

One step at a time. Keep filling in missing angles and lengths until you reach the final triangle. Do not calculate results until the end; the earlier you calculate sin's and cosine's the more inaccurate the final answer (e.g. you might be able to cancel out). There is 180 degrees in triangles. Giving you the answer is meaningless unless you're asking for confirmation of the answer you calculated.
