Answer:

QR = 5.4

Step-by-step explanation:

These pentagons are similar meaning their corresponding parts have the same scale factor.

AB to PQ  = 2 to 1.8  

2/1.8 = 10/9                        2 ÷ 1.8 = 2 ÷ 1 8/10; 2 ÷ 18/10 ; 2 × 10/18 = 20/18 ; 10/9

AB : PQ =  BC :  QR

[tex]\frac{10}{9} = \frac{6}{QR}[/tex]

10QR = 54

 QR = 54/10

  QR = 5.4
