Answer 2

x=5.4 cm

Step-by-step explanation:

In triangle PQR

AB is parallel to QR

Angle PAB=Angle PQR

Angle PBA=Angle PRQ

Reason: Corresponding angles are equal.

Therefore, $\triangle$PQR$\sim\triangle PAB$

Reason: AA Similarity postulate

When two triangles are similar then the ratio of their corresponding sides are equal.

Therefore, $\frac{PA}{PQ}=\frac{PB}{PR}=\frac{AB}{QR}$

$\frac{3.6}{x}=\frac{3.2}{4.8}$

$x=\frac{3.6\times 4.8}{3.2}=5.4cm$

Hence, the value of x=5.4 cm
