Question

The centre of a circle is ( x + 2 , x - 1 ) . Find x if the circle passes through ( 2 , -2 ) and ( 8 , -2 ) .

Answer 1

Here is your answer!!

Answer 2

Answer :

X = 3.

Explanation :

Refer to the attachement for the solution.

Formula used :

Distance formula,

$\sqrt{ {(x - x1)}^{2} + {(y - y1)}^{2} } = \: XY$

Where (x, y) is the coordinate of Xand (x1, y1) is the coordinates of Y. And XY is the line segment.

Coordinates of the centre O is (x+2,x-1)=(3+2,3-1)=(5,2).
