    Quickest 90 degree back cut is done by making a 60 or 45 line from the corner that will be the cut with a speed square, then using a scrap piece of 2xby lumber turned skinny side up, line up that 2xby on the inside of the cut line and move down from the corner until it uncovers the edge. Mark it and cut. You loose an inch or two with this method, but it is how the big boys on the FEMA teams do it.

    The initial cut is determined if you are using a flying raker or split/solid sole raker of course.

    I know this post is old but I been in RS1 class this month. We just did shoring and the way they showed us to make this cut is to use a tri-square, draw a 45 degree line starting from edge of board, measure 1.5 inch from line and mark another 45 degree line. See image.
    Drews way seems easier, but just thought I would share.

    Which is the text book way to do a 45 degree raker. It just takes math to get the cuts right on a 65 degree raker that way (65 and 25). Much easier to use the scrap wood and saves you double guessing your angles, or --gasp-- recutting lumber.

    Also, maybe you did it for picture taking reasons, but anytime cutting a lot of lumber will teach you to just place a "X" on the parts to be cut off. Writing "cut -->" will get old quick. Ever frame a house?
