Identify Similar Triangles: Identify that similar triangles have proportional sides.
Set Up Proportion: Set up the proportion using the corresponding sides of the similar triangles. Let's say the sides of triangle ABC are a, b, and c, and the sides of triangle DEF are d, e, and f. Since x=16, we have one of the sides for triangle DEF. We need to know which sides correspond to x to set up the proportion correctly.
Solve Proportion: Without loss of generality, assume side e corresponds to x. Then the proportion is eb=fc. But we don't have the values for b, c, or f, so we can't solve the proportion.
