A triangle, with its obtuse angle on the bottom right, sides labeled as follows: bottom, 9 inches,  left, 20 inches. A dashed line segment, from bottom right vertex, perpendicular to the left side, labeled, h. A dashed line segment extends the bottom side to the right. A dashed line segment from the top right vertex, perpendicular to the extended dashed side, is labeled, 12 inches.In the figure at right, find the interior height () of the obtuse triangle. Show all work.  

and are the base and height, but so are and . How can you use this fact?
