Normal reaction is zero actually means that it follows the same trajectory as the surface.This data is of no use,its a simply a projectile question.
I cant type the exact solution because it is very difiicult for begginer like me to type mathematical equation.
So i will type the method of solving.
Method 1

In that equation you can put the value of y,\theta,u and g and obtain the value of x by solving the quadratic.
Then evaluate the slope as y/x and find the tan inverse of that.
the answer will come
