Answer :

The distance of any point which lies on the circumference of the circle from the centre of the circle is called radius.


OA = OB = Radius of given Circle


taking square on both sides, we get-


OA2 = OB2


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


[using distance formula, the distance between points (x1,y1) and (x2,y2) is equal to units.]


(-2)2 + 0 = x2-4x + 4 + (-2)2


x2-4x + 4 = 0


(x-2)2 = 0


x = 2


Thus, the value of x is 2.
