**drwls**, Sunday, August 23, 2009 at 5:53amWe can't draw graphs or triangles for you here, but can tell you that A+B and A-B are the bases of isosceles triangles with two equal side lengths of 8. The apex angle is 45 degrees for A+B and 135 degrees for A-B. The vector you want is the third side. Start by drawing vector 8 with its tail at the origin and the arrowhead ponited at 45 degrees into the first quadrant. The connect (add or subtract) vector B from there.
