A map shows the number of steps you must take to get to a treasure. However, the map is old, and the last dimension is unreadable. A map shows two right triangles share a base their bases meet at a vertex. The larger right triangle has sides labeled 250 steps and 300 steps. The smaller right triangle has one side labeled 80 steps. The lengths 240 steps and 80 steps form a horizontal line and the hypotenuses of the two triangles form a single line that intersects the horizontal line.
