http://i169.photobucket.com/albums/u212/DeChiu/untitled.jpgI need to find 'L'... I do not know how I would like an explanation... yes this is homework... so don't pee in your pants... I want to know how to figure it out as well as the answer...Fastest correct response will earn 10 pts, give thumbs up if correct, thumbs down if not. This is not to insult the reasoning of other people. As long as you can logically explain it to me I do not care if you used a purple monkey to solve the problem.Flat answers or BS explanations will not earn point if you are correct.Thank you.It's law of cosines hehe...I know, I tried cutting it into 2 but I couldn't see anyway to solve it.Hgyer... That was a really crappy explanation. You're lucky I studied it for a while and you win

i forget law of sines...but u need to cut that so that it is two triangles than when u solve for the left triangle u will get a side for the right triangle and its a piece of cake.

Split it up into two triangles. You can find the length of the line that goes from one unmarked angle to the other unmarked angle. Then you will have to sides of the triangle to find L.first trianglesin(72) = x/3535*sin(72) = xx = 33.29second trianglesin(28) = 33.29/L(sin(28))*L = 33.2933.29/sin(28) = LL = 70.9
