Mazyrski [523]

Answer:

\boxed{\boxed{PQ=3.6\ in}}

Step-by-step explanation:

As it is given as ΔQRP and ΔARC are similar, so the ratio of their corresponding sides will be same.

So,

\dfrac{RC}{PR}=\dfrac{AC}{PQ}

It is given as,

RC  = 3.3

PR = 1.8

AC = 6.6

PQ = ??

Putting the values,

\Rightarrow \dfrac{3.3}{1.8}=\dfrac{6.6}{PQ}

\Rightarrow PQ=\dfrac{6.6\times 1.8}{3.3}=3.6
