------------------------

__98(800(D/40))__ = sin(2A)

(P/4)²*4(240)²

That's about as far I got. I forgot how to get rid of sine since I haven't done it in about 2 years. If some one can tell me how I can go about getting rid of the sine, or alternatively, solving the problem for A, that would be amazing. I kept the numbers unsimplified for a reason. If you wish to solve for it and simplify it, 98 = G, and 240 = M. Otherwise, I would love to know how to get rid of the sin and solve for A.
