The Attempt at a Solution
I am trying to solve for A but the sine thing has me all screwed up. This isn't for homework but I figured it might be better in this section. I get down to Sin A(4.625A + 171.87) = 229.16
I don't think I did it right at all and if I did I have no idea how to go any farther with it. Thanks for any help you guys might have.
