You rotated the page properly. It's almost never possible to get a completly perfect straight line on all edges with these raws. I pick the line that is the longest and make sure it's straight. Then make your borders. The trick is to rotate it so that you lose the least amount of pixels when you do your new borders. All I did was rotate this page 0.2 clockwise and came up with the same line as you did. The amount of rotation depends on how angled the page is. Also only rotate once. If it isn't enough step back to where you were and rotate a little more until you have your straight line.
