Question

Q.7) If the distance between point
P(2, 2) and Q(5, x) is 5, then the value
of x is.......​

Answer 1

Answer:

p

Step-by-step explanation:

p(x₁,y₁),q(x₂,y₂)

distance=(x₂-x₁)²+(y₂-y₁)²=5²

             =(5-2)²+(x-2)²=25

             =(x-2)²=16

             =>x-2=4;    x=6

             

Answer 2

d =(x₂-x₁)²+(y₂-y₁)²=5²

  =(5-2)²+(x-2)²=25

  =(x-2)²=16

   =x-2=√16

  =x-2=4

  =x =4+2

  =x=6
