Question

If the distance

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

Answer 1

Answer:

Correct option is

B

6

We have,

P=(2,2),Q=(5,x) and PQ=5

We know that

d2=(x2−x1)2+(y2−y1)2

Therefore,

PQ2=(5−2)2+(x−2)2

52=(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.
