This angle has not been cut or I would use one. All I have are dimensions. Project is a baseball ring holder in the shape of a “home plate” that I will build for a lady at the office.

it will be the the exact dimensions of a baseball home plate. 17” wide at the top, perpendicular down 8.5” and diagonally down 12”. The angle at the juncture of the 8.5” and the 12” is what I need. The difference in length of the 8.5” piece is 3/8” , 8.5” on the outside edge and 8 1/8” on the inside edge of the board, if laid on it’s edge. . I need to know that angle. Hope that makes sense? Here is a full scale view. It is 3” deep and this is the front view.
