I measured the distances from the pivot. You still have not provided the gravity at your location and the distance is still 13.5 cm to the left of the pivot for a) and 61 cm to the right of the pivot for b) and surely you can calculate this from the end of the board? ( 79-13.5 and 79 + 61 cm respectively )
