Detailed Solution

If the points A(4,3) and B(x,5) are on the circle with center O(2,3), then the value of x is 2.
We have been given,
The points A(4,3) and B(x,5) are on the circle.
O(2,3) is the center of the circle.
Now it is clear that one of the circumferential points and the center point share the same y coordinate.
The radius is therefore 2 units.
Using the distance formula between point B and the center of the circle,
D=x2-x12+y2-y12
Substituting x2=x, x1=2, y2=5, and y1=3, in the formula,
x-22+5-32
(x-2)2=0
x=2
Therefore, the value of ‘x’ is 2.
