Find the distance between the point `P(6, 5, 9)`and the plane determined by the points `A (3, -1, 2)`, `B (5, 2, 4)`and `C( -1, -1, 6)`.

Explanation

`|[(x-x_1),(y-y_1),(z-z_1)],[(x_2-x_1),(y_2-y_1),(z_2-z_1)]|`


`|[x-x_1,y-y_1,z-z_1],[x_2-x_1,y_2-y_1,z_2-z_1],[x_3-x_1,y_3-y_1,z_3-z_1]|`



The plane is passing through points `A (x_1, y_1, z_1)`, `B (x_2, y_2, z_2)` and `C (x_3, y_3, z_3)`


`|[x-x_1,y-y_1,z-z_1],[x_2-x_1,y_2-y_1,z_2-z_1],[x_3-x_1,y_3-y_1,z_3-z_1]|`
