PQ is a diameter of the circle with centre at O. The tengent drawn at A on the circle intersect the extended PQ at R. If `angle PRA=45^(@),` then `angle OAP=`

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 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.

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 of a circle with centre O intersects the diameter PQ of the circle (when extended) at the point B. If angle BAP = 125^@ , then angle AQP is equal to: केंद्र O के साथ एक वृत्त के बिंदु A पर स्पश्रेखा, बिंदु , B पर वृत्त के व्यास PQ ( जब विस्तारित) को काटती है यदि angle BAP = 125^@ है, तो angle AQP के ज्ञात करें ।

If PQ be a diamter of a circle with centre at O and if PR= RQ, then the value of angle RPQ is

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:

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
