Bend Along a diagonal line

Hi I am trying to bend a flat plate 90 degrees along a line that is diagonal (about 5 degrees) to the edge
its overall 240x220 mm and 10 mm thick.
The idea is that one face is vertical and the other face is on a 5 degree slope
Any ideas.
Maybe Freedo but which one?

You should specify the radius of the bend.

Following your description, I get that, see this SU file.
