Please Help this is urgent!! Anyone know how to prove that? Is it that I just pick a whole bunch of random degrees and say look this is all I have to prove it. please help!!

Horizontal distance= velocity^2 * Sin(2X)/ acceleration of gravity
Sin (2X)= 2* 45 degrees= Sin 90= 1 (and 1 is the greatest value of the Sin)
so, horizontal distance when the angle is 45 degrees = velocity^2/ acceleration of gravity
And -I guess- this means that maximum distance is reached with 45 degrees.

You need to find a formula for the distance based on the angle.
Once you get this formula use calculus to find the maximum.
