Consider the curve C:y^(2)-8x-4y+28=0. Tangents TP and TQ are drawn on C at P(5,6) and Q(5,-2) . Also normals at P and Q meet at R. The coordinates of circumcentre of Delta PQR, is

consider the parabola y^(2)-8x-4y+28=0 then angle between a pair of tangents drawn at the end of the chord y+5t=tx+2 of curve.

The common tangents to y^(2)=8x and the curve 3x^(2)-y^(2)=3 meet y^(2)=8x at P and Q. The length of PQ is

Consider a curve C:y^(2)-8x-2y-15=0 in which two tangents T_(1) and T_(2) are drawn from P(-4,1). Statement 1:T_(1) and T_(2) are mutually perpendicular tangents.Statement 2: Point P lies on the axis of curve C.

A line y=2x+c intersects the circle x^(2)+y^(2)-2x-4y+1=0 at P and Q. If the tangents at P and Q to the circle intersect at a right angle,then |c| is equal to
