Best ResponseYou've already chosen the best response.0I am able to determine the simple things but I can't see how to find the third angle. Since it is not a right triangle I can't use pythagorean, and I don't have enough information to use law of sines, or cosines. The only thing I could think of is somehow converting the T= 600lb into ft somehow (but it does not seem possible)

Best ResponseYou've already chosen the best response.1if so, then we know BD and DC, and AC is given knowing AD and BD. if D is a right triangle, gives you the 2 legs of a right triangle and the trig functions can all be ratioed
