If a point A(4,3)B(x,5) are on a circle with center O(2,3) Find x

1.	If a point A(4,3)B(x,5) are on a circle with center O(2,3) Find x
Answer» A and B are on circleso OA=OB=rOA^2=OB^2(4-2)^2 +(3-3)^2=(x-2)^2+(5-3)^2or 4+0=(x-2)^2+4(x-2)^2=0x-2=0x=2 Given centre of circle is O(2, 3)\xa0Points on the circle are A(4, 3) and B(x, 5)\xa0OA =OB (Radii) à (1)\xa0Recall the distance between two points formula\xa0\xa0Squaring on both the sides, we get\xa0\xa0\xa0x – 2 = 0\xa0∴ x = 2 What is A and B radius,diametre or cord
