Math Help?

[quote=Jams XD]I'm fairly certain that it's 36 degrees, but the explaination is quite lengthy. :\[/quote]

[quote=NinjaGinge][quote=screwblum] [center] Supposed to be a College level problem. I am confused, any help? [img=http://img26.imageshack.us/img26/6350/mathproblemk.png] inb4: Yes this was made in paint. And I am quite sure it's not equilateral. [/center] [/quote] Let angle CAB be a ABC be c BCD be b CDB be d ACB=CAB CBD=CDB a+b = 180 b + 2d = 180 a + 2d + c = 180 2a + c = 180 four equations four unknowns. solve for d[/quote]

[quote=NinjaGinge]I didnt take the time to check the math. 36 may be right. def not a college level problem. Geometry and systems of equations.[/quote]

[quote=screwblum]It's not THAT crappy of a drawing. I traced the triangle (Put it over the screen). It is supposed to be leaning to the right a little if thats what your referring to.[/quote]

[quote=caucheka]wait, how is it supposed to be leaning to the right? 2 of the sides are the same thus making it isosceles, meaning angle a and b are the same[/quote]

[quote=caucheka]yep its 36. [img]http://img200.imageshack.us/img200/1750/yepc.png[/img] good luck showing your work though on how to figure that out.[/quote]

[quote=screwblum]Thank you Cauch and everyone who helped. Ill try to figure out how you did that and right it down.[/quote]

[quote=Toshabi]You still haven't animated the picture and/or corrected the proportions in your first image. How are you suppose to pass if you don't have proportions right?[/quote]
