From a point `A(-3, 5)` tangents are drawn to the circle. If `BC` is the contact, then the circumcentre of triangle `ABC` is

From a point R(5,8) two tangents RP and RQ are drawn to a given circle s=0 whose radius is 5. If circumcentre of the triangle PQR is (2, 3),then the equation of circle S=0 is

From a point R(5, 8) two tangents RP and RQ are drawn to a given circle s=0 whose radius is 5. If circumcentre of the triangle PQR is (2, 3), then the equation of circle S = 0 is

If tangents PA and PB are drawn to circle (x+3)^(2)+(y-2)^(2)=1 from a variable point P on y^(2)=4x, then the equation of the tangent of slope 1 to the locus of the circumcentre of triangle PAB IS

Prove that if two tangents are drawn to a circle from a point outside it, then the line segments joining the point of contacts and the exterior point are equal.
