Use the image to answer the question.
An illustration shows two quadrilaterals, one big and one small. In the small quadrilateral, one side measures 2 and its opposite side measures 5. In the big quadrilateral, the side corresponding to 2 in the small quadrilateral measures 3.6 and the side corresponding to 5 measures x.
The two quadrilaterals are similar. What is the value of x ?

To find the value of x, we can set up a proportion based on the corresponding sides of the two quadrilaterals:
2/5 = 3.6/x
To solve for x, we can cross-multiply:
2x = 5 * 3.6
2x = 18
Divide both sides by 2 to isolate x:
x = 18 / 2
x = 9
Therefore, the value of x is 9.
