The following two triangles are similar to each other. Find the length of the missing side.
There are two triangles. The one on the right is smaller, and the one on the left is larger. Both triangles have unequal sides. For the smaller triangle, its shortest side is marked as 17.5 m, its second shortest side is marked as 42 m, and its longest side is marked as x m. For the bigger triangle, its shortest side is marked as 28 m, its second shortest side is marked as 67.2 m, and its longest side is marked as 72.8 m.
Use m for meters.
