Here's what I'd do:

The important thing is that the angle on the blocks matches the angle
on the sides for a good glue joint. I wouldn't trust myself to be
able to measure anything down to less than a degree, but I can handle
"the same". You're going to need to cut the sides with the compound
angles, so I'd attach blocks to the corners before cutting, and cut
the blocks and sides at the same time. Or cut the blocks using the
same setup as the sides.
