Answer:

[tex] x = 3.6 [/tex]

Step-by-step explanation:

Since Quadrilateral ABCD ~ PQRS, therefore:

[tex] \frac{AB}{PQ} = \frac{BC}{QR} = \frac{CD}{RS} = \frac{DA}{SP} [/tex]

Let's find the value of x by using the ratio of two corresponding sides of both quadrilaterals. Let's use:

[tex] \frac{CD}{RS} = \frac{DA}{SP} [/tex]

CD = 5

RS = 4.5

DA = 4

SP = x

[tex] \frac{5}{4.5} = \frac{4}{x} [/tex]

Cross multiply

[tex] 5*x = 4.5*4 [/tex]

[tex] 5x = 18 [/tex]

Divide both sides by 5

[tex] x = \frac{18}{5} [/tex]

[tex] x = 3.6 [/tex]
