Dear student,

Let the inclination of the plane be @ and projectile is thrown making an angle § with the incline.
Now, projectile makes an angle @+§ with the ground. Resolve the velocity along and perpendicular to the plane,
[assume x axis along the plane and y axis perpendicular to the plane]
Vx= v cos §
Vy=v sin §.
Also, resolve g along and perp to plane
g x= g sin @
g y= g cos @.

On solving we get the answer=6V/g root (1+8sin^2 theta)
