From a point P outside a circle with centre at C, tangents PA and PB are drawn such that `1/(CA)^2+ 1/(PA)^2=1/16`, then the length of chord AB is

From a point P outside a circle with centre at C, tangents PA and PB are drawn such that (1)/((CA)^(2))+(1)/((PA)^(2))=(1)/(16) , then fid the length of chord AB.

From a point P outside a circle with centre O , tangents PA and PB are drawn to the circle. Prove that OP is the right bisector of the line segment AB .

If tangents PA and PB are drawn from P(-1, 2) to y^(2) = 4x then

If PA and PB are tangents from an outside point P such that PA=10cm and /_APB=60o. Find the length of chord AB

From the point P(4,-4) tangents PA and PB are drawn to the circle x^(2)+y^(2)-6x+2y+5=0 whose centre is C then Length of AB

In the given figure, from the point P two tangents PA and PB are drawn to a circle with centre O and radius 5cm. From the point O, OC and OD are drawn parallel to PA and PB respectively. If the length of the chord AB is 5cm, then what is the value of (in degrees) of angleCOD ?

AB is a chord of circle with centre O. At B, a tangent PB is drawn such that its length is 24 cm. The distance of P from the centre is 26 cm. If the chord AB is 16 cm, find its distance from the centre.
