We have a sun shelf on the house; when it's mounted, it tilts 30 degrees out from the house.
In the corners, it should be mitered at 45 degrees, but that's only when it's at the right angle. However, when cutting in the miter saw, it's lying down, then it's about 40 degrees and about 22 degrees side tilt, but it's not exact.
Does anyone know the exact angles? Or how to calculate them?
