CP and CQ are tangents to a circle with centre O. ARB is another tangent touching the circle at R. If$$ CP = 11 cm, BC =7 cm$$, then the length BR is :

In Fig. 3, PQ and PR are the tangents to the circle with center O such that $$\angle QPR = 50^{\circ}.$$
Then $$\angle OQR$$ is equal to:

In the given  figure, the length of PR is :

In the given figure, if PT is a tangent of the circle with center O and $$\angle TPO = 25^{\circ} $$, then the
the measure of x is :

In above Fig. 2, $$AB$$, $$AC$$ and $$ PQ$$ are tangents. If $$AB = 5 \,  \mathrm{cm}$$ and $$PQ= PB+QC$$, then perimeter of $$\Delta APQ$$ is:

If the angle between two radii of a circle is $$140^{\circ}$$, then the angle between the tangents at the ends of the radii is :

In the figure, if the semiperimeter of $$\triangle ABC = 23$$ cm, then AF + BD + CE is:

In the given quadrilateral $$OQPR,$$ if $$\angle  QPR=50^\circ $$ then $$\angle  QOR $$ equals

In the given figure, a circle touches the side $$BC$$ of $$\triangle ABC$$ at $$P$$ and $$AB$$ and $$AC$$ produced at $$Q$$ and $$R$$ respectively. If $$AQ=15cm$$, find the perimeter of $$\triangle ABC$$.

To draw a pair of tangents to a circle which are inclined to each other at an angle of $$ 35^{\circ}$$, it is required to draw tangents at the end point of those two radii of the circle, the angle between them is:
