Minecraft ps3 trophy

I really want these three trophies in minecraft ps3 edition
The one about entering the end
The one about killing the ended dragon
And the one about killing a skeleton 50 m away. Can any one help me get these trophies? I have nothing to offer but can any one help? Add me narutofandbz
Please be able to have the portal ready and such. I will try to help you back in any way

To enter the End you need to find a stronghold. Once you've located that, there should be an inactive End portal in there - to activate it you need to put ender eyes in each of the slots (I think there's 10? Not sure). Once in the End you face off against an Ender dragon. Just beat that.

Killing a skeleton from 50m away is pretty hard, but the best method for me was to use a sword to weaken a skeleton, build a tall tower close to the skeleton, and shoot an arrow from the top.
