Projectile motion, Cat jumping off table

epsilonaught

1. The problem statement, all variables and given/known data
A cat jumps off of the table with a velocity vi at an angle θ. The table is h meters tall. How far away from the table is the cat?
V(x) = ViCosθ
V(y) = ViSinθ

2. Relevant equations
I first solved for time using 0 = Xi + Vit +1/2a(t^2)


3. The attempt at a solution
I got time as
t = V_iSinθ-√(V_i²Sinθ² + 2gh) / g


But my teacher got a answer slightly different. Am I solving for time the write why? I think so. If not, What am I missing? Thanks

The negative sign should be positive in the expression of t.
