(adsbygoogle = window.adsbygoogle || []).push({}); HELP!!! A question on Kinematics in 2D & 3D?

1. The problem statement, all variables and given/known data

A gun is placed at the base of a hill whose slope makes an angle alpha with the horizontal. If the gun is set at an angle theta with the horizontal and has a muzzle velocity Vo, find the distance, measured along the hill, at which the bullet will fall.

3. The attempt at a solution

I know that I need to separate this question in to two equations/ two 1D problems (x-axis and y axis)

Velocity for x = Vo* cos(Θ-α) - g * t * sin(α)

X = Xo + Vo * t * cos(Θ-α) - 0.5 * g * t^2 * sin(α)

Velocity for y = Vo* sin(Θ-α) - g * t * cos(α)

Y = Yo + Vo * t * sin(Θ-α) - 0.5 * g * t^2 * cos(α)

But how can i figure out Vo, Θ, α, Xo, t and Yo

Please help me.
