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

In fig.1,PQ is a tangent at a point C to a circle with centre O if AB is a diameter and angle CAB=30^(@), find angle PCA.

PQ is tangent at a point R of the circle with centre O. If ST is a diameter of the circle and angle TRQ = 30^(@) find angle PRS

In the given figure, PQ is a tangent at a point R of the circle with centre O. If angle TRQ = 30^(@) , then angle PRS is equal to

AB is a diameter of a circle with centre O and AT is a tangent. If angle AOQ = 58^(@) find angle ATQ .

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.

In the figure, PA is a tangent from an external point P to the circle with centre O and diameter AB. If angle POB = 110^@ , then the measure of angle APO is:

In the given figure,PQ is tangent at a point R of the circle with centre O.If,find m/_PRS .

In fig. PQ is a tangent to length 6cm to the circle with centre O and angle OQP=60^@ . Find OQ

The tangent at a point C of a circle and a diameter AB when extended intersect at P. If anglePCA=110^(@) "find" angleCBA .
