If the angle between two tangents drawn from an external point P to a circle of radius 'a' and center O , is 60^(@), then find the length of OP.

If the angle between two tangents drawn from an external point ‘P’ to a circle of radius ‘r’ and centre O is 60^(@) , then find the length of OP.

If angle between two tangents drawn from a point P to a circle of radius a and centre 0 is 60^(@) then OP=asqrt3 .

If angle between two tangents drawn from a point P to a circle of radius 'a' and the centre O is 90^(@) then prove that OP=sqrt(a)

Write True or False and justify your answer: If angle between two tangents drawn from a point P to a circle of radius a and centre O is 60^(@) then OP=asqrt3 .

Write true or false and state reason: If angle between two tangents drawn from a point P to a circle of radius a and centre O is 90^(@) then OP=asqrt2 .

PR and PS are two tangents drawn from a extental point P of the Circle with centre at O. If PR =8 cm and angle RPO=60^(@), then the length of PS=

What is the angle between the two tangents drawn from an external point to a circle and the angle subtended by the line-segment joining the points of the contact at the centre.

Prove that the angle between two tangents drawn from an external point to a circle is supplementary to the angle subtended by the line segments joining the points of contact at the centre.
