Consider the reaction between the particle and the hemisphere. What is it, and what value will it take as the particle is just about to leave the sphere?

Resolve radially to get the centripetal force (mv^2/r) that includes the reaction force, then solve for the reaction force and set the reaction force to 0 (flies off the surface, so reaction is zero) then re-arrange for cosine theta.

Edit: too late.
