NO 15. If the angle between two tangents drawn from an external point P to a circle of radius a and centre O is 60° then find the length of OP. [CBSE 2017]

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 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 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 .

The length of tangent from an external point P on a circle with centre 0 is always less than OP.

The length of tangent from an external point P on a circle with centre 0 is always less than OP.

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 .

If the length of the tangent from an external point P to a circle of radius 10cm. Is 24cm, then the distance of P from the centre is
