This pair of figures is similar. find the missing side.

The missing side “x” is 2.

Step-by-step explanation:

From the given figure, we came to know that these are “similar triangles” where the ratio of the one “corresponding side” of a triangle is equal to the other two “corresponding sides” of a triangle.

Let the triangles be ∆ABC and ∆DEF

From similarity of triangle rule the sides,

Given that,  

AB = x, DE = 8, BC = 4 and EF = 16

x = 2

Therefore, we found the missing side x = 2
