# Monkey and tree - projectile motion

The famous scenario: A hunter is trying to shoot a Monkey hanging from a tree. However, this question doesn't mention the monkey jumping down from the tree or trying to escape. (The hunter uses a tranquilizer gun, so I'm guessing the sound goes unheard.) We only know two things:

1) The height at which the monkey is hanging. 2) Distance of the monkey from the hunter.

(The hunter aims his gun directly at the monkey.)

I've solved it using this approach:

Solving for initial velocity required to launch a projectile to a given destination at a different height

Does this fit the bill or am I missing something?

Why does the answer have $d\, \text{tan}\, \theta + h$ in denominator? I'm getting $d\, \text{tan}\, \theta- h=0$ in the denominator!

Does denominator = $0$ simply mean that it's not possible? In other words, does the monkey have to fall down if the bullet has to hit the monkey?
