If Fig. 'O' is the centre of the circle Determine `angleAQB and angleAMB` if PA and PB are tangents and `angleAPB = 75^@`.

In the given figure, O is the centre of the circle angleAOB=90^@ Find m angleAPB

In fig.O is Centre of circle,find x^(@)

In Fig O is the centre of a circle and AT is a tangent at point A . what is the measure of angle BAT ?

In the given figure, O is the centre of the circle, PA and PB are tangents to the circle then find angle AQB .

Two circles intersect each other at P and Q. PA and PB are two diameters. Then angleAQB is

O is the centre of the circle and two tangents are drawn from a point P to this circle at points A and B. If angleAOP=50^(@) , then what is the value (in degrees) of angleAPB ?

O is the centre of the circle. OP = 5 and OT = 4, and AB = 8. The line PT is a tangent to the circle. Find PB

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 .

O is the centre on the circle. PA and PB are tangent segments. Then the quadrilateral AOBP is :

Two circles intersect each other at point P an Q. If PA and PB are two diameter then find angleAQB .
