2d-physics

I'm making a thing that launches projectiles in 2D. Its projectiles are fired with a set initial velocity, and are only affected by gravity. Assuming that its target is within range, and that there aren't any obstacles, how would my thing find the appropriate angle at which to launch its projectile (in radians)?

The equation for this is found here: Wikipedia: Angle Required to Hit Coordinate

Sadly, I'm not a physicist (a.k.a. can't read smart people math) and am having a hard time reading its breakdown. If not only for the sake of anybody else that might read this other than myself, would anybody be kind enough to break the equation down into baby words please?

I'm a software engineer that's new to game programming so forgive me if this is a dumb question as I don't know that much about game engines.
