Could you also first have solved for alpha by dividing eq 2 by eq 1? The "a's" would cancel and you would get sin(x)/cos(x) = 4/3 which is basically saying tan(x) = 4/3?

Yes. Then you can get sin(x) = 4/sqrt(4^2+3^2) = 4/5. Similarly cos(x) = 3/5. You can then substitute in equation 1 or 2 to get a = 5.
