How do you eliminate this?

V3(cos A) + V4(cos 30) = 5 Equation 1

V3(sin A) = -(V4)(sin 30) Equation 2

V3^2 + V4^2 = 25 Equation 3

2. Relevant equations

3. The attempt at a solution

I let

x= V3 ; y=V4

and I got

x(cos A) + y ((sqrt)3) = 10

-2x(sin A) = y

x^2 + y^2 = 25

but I'm totally stuck... any help?
