the quickest way to cut the angle is to use a bevel square. get your angle i think yours was around 70 degrees. using a protractor line up the 0 and 180 degree line with the edge of a piece of timber and mark your angle. take the bevel square press it up against the edge of the timber and line up the 90 degree mark with the center of the bevel square and the angle you marked with the moving part of the bevel square. tighten butterfly nut and you have your angle. place the bevel square on the table saw and move the blade to the angle you have on the bevel square. otherwise you can use a piece of scrap timber. mark as i said previously. draw a line between the 90 degree mark on the bottom edge of the timber and the angle you have marked. cut along this line with a jig saw and you have your angle
