Answer by rapture(86) (Show Source): You can put this solution on YOUR website!
tan(6°) = 2/(x + d)
tan(15°) = d/2
Above you have two trigonometric equations in two unknowns, d and x. Solve it as an algebra system of equations from algebra 2. Take it from here. Good luck!

The setup by "rapture" is incorrect.
The correct setup is this
tan(6°) = 2/(x + d)
tan(15°) = 2/d,
where d and x are distances in kilometers.
It implies
x = - .
