If A geometric diagram shows two large triangles. The upper triangle has vertices labeled A at the top left, B at the bottom left, and C at the top right. The lower triangle has vertices labeled F at the bottom left, D at the bottom right, and E at the top right. The slanted sides of the triangles run parallel to each other. The vertical sides on the left and right edges appear straight, with A above B on the left and E above D on the right.

What is the ratio of the corresponding sides?  A geometric diagram shows two quadrilaterals placed side by side. The smaller quadrilateral on the left is labeled A, B, C, and D. Point A is on the top left, B on the top right, C on the bottom right, and D on the bottom left. The top side AB is longer than the bottom side CD. The sides AD and BC slope inward as they move downward to the bottom side. Side AB is labled with a length of 24 inches and side AD is labled with a length of 38 inches. The larger quadrilateral on the right is labeled E, F, G, and H. Point E is on the bottom left, F on the bottom right, G on the top right, and H on the top left. The bottom side EF is longer than the top side GH. The sides EH and FG slope outward as they move downward to the bottom side. Side EF is labled with a length of 36 inches and side EH is labled with the variable x.
