# If the Point a (4,3) and B ( X,5) Lies on a Circle with the Centre O (2,3) . Find the Value of X. - Mathematics

If the point A (4,3) and B ( x,5)  lies on a circle with the centre o (2,3) . Find the value of x.

#### Solution

Given, the points A(4,3) and B(x,5)  lie on a circle with center o(2,3) . Then OA = OB

Also (OA)^2 = (OB)^2

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

⇒(2)^2+(0)^2=(x-2)^2 +(2)^2

⇒ 4=(x-2)^2 +4

⇒(x-2)^2 =0

⇒ x -2 = 0

⇒ x =2

Therefore,  x= 2
