PQ is a tangent drawn from a point P to a circle with centre O and QOR is a diameter of the circle such that `angle POR =120^(@)`. Find `angle OPQ`.

PQ is tangent drawn from point P to a circle with centre O and QR is a diameter of the circle, such that anglePOR=120^(@) . Then, angleOPQ=…….. .

PQ is a tangent drawn from a point P to a circle with centre O and QOR is a diameter of the circle such that /_POR=120o, then /_OPQ is 60o (b) 45o (c) 30o (d) 90o

PQ is a tangent drawn from an external point P to a circle with center O, angle QOR is the diameter of the circle. If angle POR = 120^(@) . What is the measure of angle OPQ ?

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

Two tangents are drawn from a point P on the circle at point A and B. O is the centre of the circle. If angleAOP=60^(@) then find angleAPB .

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.

In Fig,PQ is a tangent from an external point P to a circle with centre O and OP cuts the circle at T and QOR is a diameter.If /_POR=130^(@) and S is a point on the circle, find /_1+/_2
