If two tangents are inclined at 60^(@) are drawn to a circle of radius 3cm then find length of each tangent. OR PQ is a tangent to a circle with centre O at point P. If Delta OPQ is an isosceles triangle, then find angle OQP.

PQ is a tangent to a circle with centre O at the point P . If DeltaOPQ is an isoceless triangle, then /_OQP is equal to

PQ is a tangent to a circle with centre O at the point P. If DeltaOPQ is an isosceles triangle, then angleOQP=………. .

P Q is a tangent to a circle with centre O at the point P . If /_\ O P Q is an isosceles triangle, then /_O Q P is equal to :

PQ is a tangent to a circle with centre O at the point P. If OPQ is an isosceles triangle, then /_OQP is equal to 30o (b) 45o(c)600 (d) 90o

At point 'P' on a circle, PQ is a tangent and 'O' is the centre of the circle. If triangleOPQ is an isosceles triangle, then /_OQP is equal to

In Figure 4,PQ and PR are tangents drawn to a circle with centre O from an external point P . If /_PRQ=70^(@), then find /_QPR and /_OQR

In 2, PQ is a tangent at a point C to circle with centre O. If AB is a diameter and angleCAB=30^(@) then find anglePCA .

In the figure, PQ is a tangent to a circle with centre O. QR=RO . If PQ= 3 sqrt(3) cm and ORQ is a line segment, find the radius of the circle.

Line PQ is a tangent to the circle at point A, arc AB~=arc AC . Prove that triangle ABC is isosceles triangle.
