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

smaller shape: 2 on left 5 on right
bigger shape: 3.6 as 2 and x as 5

To determine the value of x, we can set up a proportion using the corresponding sides of the two similar quadrilaterals:

smaller shape: 2 on left, 5 on right
bigger shape: 3.6 as 2 and x as 5

The proportion can be written as:

2/5 = 3.6/x

To solve for x, we can cross-multiply and then divide:

2x = 5 * 3.6
2x = 18
x = 18/2
x = 9

Therefore, the value of x is 9.
