In Figure 1, O is the centre of a circle, PQ is a chord and PT is the tangent at P. If angle POQ = 70°, then angleTPQ is equal to

In figure, if O is the centre of a circle, PQ is a chord and the tangent PR at P makes an angle of 50^(@) with PQ , then anglePOQ is equal to

In the given figure ,'O is the centre of circle ,PQ is a chord and the tangent PR at P makes an angle of 50^(@) with PQ ,then anglePOQ is equal to :

In figure, if 0 is the centre of a circle, PQ is a chord and the tangent PR at P makes an angle of 50^(@) with PQ, then anglePOQ is equal to

In Fig , O is the centre of a circle , PQ is a chord and the tangent PR at P makes an angle of 50^@ with PQ. Find anglePOQ .

In figure if PR is tangent to the circle at P and O is the centre of the circle then angle POQ is

In Figure PQ is a chord of a circle with centre O and PT is a tangent. If QPT =60^@ so, find PRQ.

In figure PQ is tangent to the circle with centre at O at the point B , if angle AOB = 100^(@) , then angle ABP is equal to
