Not Ranked
Well... can't tell from your description, but if the 12.25 is coming down from the top, and the 8.75 is going back from the the front to where the 12.25 lands, then you are more like 54.5 degrees. Do the inverse tan function of (12.25/8.25) on your calculator... assuming a right triangle (one angle is 90 degrees). If not, try to remeasure with 90 degrees between the down leg and the back leg, and we'll recalculate it...
