How to Convert an Angle into `Vector.new()`?

I’m coding a sliding mechanic that maintains velocity when you slide on a wedge. I’ve used Raycasting and mathematical formulas to obtain the angle I needed, but I can’t seem to make the linear velocity parallel to the slope [see screenshot for a better explanation].

If anyone knows how I could do this, I’m all ears because my last line of script doesn’t take the real angle into account.

local function Slide()
    print("Slide")
    
    local PartSize = SlideDownRaycastResult.Instance.Size
    local X = PartSize.Z^2 + PartSize.Y^2
    local Angle = math.deg(SlideDownRaycastResult.Instance.Size.Y/math.sqrt(X))
    
    
    LinearVelocity.MaxForce = 40000
    
    local Force = 5
    LinearVelocity.VectorVelocity = SlideDownRaycastResult.Instance.CFrame.UpVector * -1 * Force + Vector3.new(0,-Angle,-Angle)

end

You could try using Vector3:Cross() to obtain the vector.

local direction = -humanoidRootPart.CFrame.RightVector:Cross(SlideDownRaycastResult.Normal)
LinearVelocity.VectorVelocity = direction * Force

You can read this tutorial for more info on how it works:
