8. Similar Triangles Example: Solution: Find the length of x. To find x you need to put corresponding sides in a ratio. In this triangle 17 corresponds to 7 and 12 corresponds to x. So our ratio is: x 12 = 7 17 17x = 84 x = 4.941 Solve each triangle for the indicated variable. 1. Find the length of x. [ x = 48 9 ] 2. Find the length of y. [ x = 16.5 ] 3. Find the length of x.
