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

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 a diameter of the circle with centre at O. The tangent drawn at C on the circle intersects externded PQ at R. If angle CPO =30^(@), then find the value of angle QCR.

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 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, O is the centre and BOA is a diameter of the circle. A tangent drawn to the circels at the point P intersects the extended BA at the point T. If angle PBO=30^(@), find the value of angle PAT.

In the given figure, PQ is the tangent at a point C on a circle with centre O. If AB is a diameter and |__CAB=30^(@) , find |__PCA .

The tangent at a point A of a circle with centre O intersects the diameter PQ of the circle (when extended) at the point B. If angle BAP = 125^(@) , then angleAQP is equal to :

The tangent at a point A on a circle with center O intersects the diameter PQ of the circle, when extended,at point B. If angleBAQ=105^(@) , then angleAPQ is equal to:
