Lay a piece of trim on the skirt and mark the top on the wall out past the angle of the skirt. Now lay that piece of trim on the other plane of the skirt angle and mark the top of the trim on the wall at the angle.
See where the top intersects at the angle of the trim on the wall? You want to lay a scrap piece of flat scrap the same width as the trim piece on the skirt, let it go out past the intersecting angle point. See where the two lines on the wall intersect at the angle. Make a dot on the top of your flat piece where the two lines on the wall intersect, now before you move the trim piece, make a mark on the bottom of the flat piece at the intersection point of the skirt.
Flip your flat piece over and draw a line from dot to dot and that is your angle. Go to the miter saw and cut along that line. See what the angle is on your saw. Flip the flat piece over and lay it on your saw as that will be the way your actual trim will lay to be cut.
See how you will need to cut in the other direction as you just cut the back of the flat piece. Do the other pieces the same way but they may be a different angle so cut the flat pieces and dry fit them to see if you need to adjust the cut a little.
