1. Answer:

   We have,

   P=(2,2),Q=(5,x) and PQ=5

   We know that

   d

   2

   =(x

   2

   −x

   1

   )

   2

   +(y

   2

   −y

   1

   )

   2

   Therefore,

   PQ

   2

   =(5−2)

   2

   +(x−2)

   2

   5

   2

   =(3)

   2

   +(x−2)

   2

   25=9+(x−2)

   2

   (x−2)

   2

   =16

   x−2=±4

   x=6 or x=−2

   Hence, this is the answer.
