What is the ratio of the area of ABC to the area of ABD? A graph plots four points (0, 0) labeled A, (0, 1) labeled B, (9, 12) labeled C, and (16, 12) labeled D. Three lines connecting A C, C D, and A D completes a shaded triangle, and lines connecting A B, B C and A C and the area is shaded. A. B. C. D.
