The two quadrilateral are similar. What is the value of x?

Quadrilateral 1 has a side of 2 and 5.
Quadrilateral 2 had a side of 3.6 and x.

To determine the value of x, we can use the corresponding sides ratios of the similar quadrilaterals.

The ratio of the corresponding sides of Quadrilateral 1 and Quadrilateral 2 is:
2/3.6 = 5/x

To solve for x, we can cross multiply and simplify the equation:
2x = 3.6 * 5
2x = 18
x = 18/2
x = 9

Therefore, the value of x is 9.
