PQ=2PT=2 \times 12=24\Rightarrow QW=PQ+PW=24+8=32 \\ \hat{W} \:  is  \: shared, \widehat{PXW}=\widehat{WQX}\Rightarrow \bigtriangleup PWX\cong \bigtriangleup XWQ \\ \Rightarrow  \frac{WX}{QW}   =  \frac{PW}{WX}  \\ \Rightarrow  {WX}^{2}  = PW.QW = 8 \times 24 = 192\Rightarrow WX =  \sqrt{192}  = 8 \sqrt{3}\: units
