Triangle ABC has vertices A(0,8), B(2,0), C(6,0). A vertical line intersects AC at R and BC at S, forming triangle RSC. If the area of triangle RSC is 12, determine the positive difference of the x and y coordinates of point R.
" If the area of triangle RSC is 12..."
But it is not! The largest area of ΔRSC is 10.67 and that's when line RS passes through x=2
