PA and PB are two tangents drawn from an external point P to a circle with centre C and radius=4cm If `PA_|_PB` then length of each tangent is

PA and PB are two tangents drawn from an external point Pto a circle with centre C and radius =4cm If PA perp PB then length of each tangent is

In figure ,PA and PB are two tangents drawn from an external point P to a circle with centre C and radius 4 cm .If Pabot PB ,then the length of each tangent is :

The two tangents from an external points P to a circle with centre at O are PA and PB. If angle APB=70^(@) then the value of angle AOB is

The two tangents from an external points P to a circle with centre at O are PA and PB. If angle APB=70^(@) then the value of angle AOB is

PA and PB are two tangents drawn from an external point P at the points A and B on a circle with centre O.If another tangent to the circle intersects PA and PB at L and M respectively,show that LM=AL+BM.

PA and PB are two tangents drawn from an external point P at the points A and B on a circle C(0,r).Prove that OP_|_AB

Two tangents PA and PB are drawn from an external point P to a circle with centre at O. If AOB = 105^(@) the A hat(P) B is :

In the adjoining figure,PA and PB are tangents from P to a circle with center C.If the radius of the circle is 4cm and PA perpendicular PB.Find the length of the tangent.
