Homework Statement
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
Homework Equations
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?
