*From a physics questions with an airplane and wind, I get two equations (with angles in degrees) and must solve for angle A:*

250 cos(A) = V cos(-23) - 80 cos(-45)

250 sin(A) = V sin(-23) - 80 sin(-45)

250 cos(A) = .92V - 56.6

250 sin(A) = -.39V + 56.6

*Solving for V in the first equation...*

V = (250 cos(A) + 56.6) / .92 = 271.6 cos(A) + 61.49

*Substituting for V in the second equation...*

250 sin(A) = -.39 (271.6 cos(A) + 61.49) +56.6

250 sin(A) = -106.1 cos(A) + 32.6

How do I solve for the angle A?

Thank you
