# If the Points A(4,3) and B( X,5) Lie on the Circle with Center O(2,3 ) Find the Value of X . - Mathematics

If the points  A(4,3)  and B( x,5) lie on the circle with center  O(2,3 ) find the value of x .

#### Solution

The given points A(4, 3) and B(x, 5) lie on the circle with center O(2, 3).  Then, OA = OB

⇒ sqrt((x-2)^2 +(5-3)^2) = sqrt((4-2)^2 +(3-3)^2)

⇒ (x-2)^2 +2^2 =2^2+0^2

⇒ (x-2)^2 = (2^2 -2^2)

⇒ (x-2)^2=0

⇒  x - 2 = 0

⇒ x = 2

Hence, the value of x = 2
