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 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 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 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 PQR is the tangent to a circle at Q whose centre is O, AB is a chord parallel to PR and angleBQR=70^(@) then angleAQB is equal to

In figure, if PQR is the tangent to a circle at Q whose centre is O, AB is a chord parallel to PR and angleBQR=70^(@) then angleAQB is equal to

In the adjoining figure 'O' is the centre of the circle and PQ, PR and ST are the three tangents. angleQPR = 50^(@) , then the value of angleSOT is :
