How to give a wall panel the option of different angles?

I have a panel that I have made with 3 types of materiel and I want to be able to have the top adjust to different angles.

Panel%20Angle

Thank you,

check this thread:

I had seen that one but I want pick a pitch for the angel.

Well so, the basic idea is that you divide the top part in rectangle that has its bounding box aligned with its (internal) Axes and triangled parts that have one 90 degrees angle.
You actually ‘scale’ the bounding box of the part, not its individual edges…
More luck if you upload the panel

Here is something you could do:
