A circle centred at 'O' has radius 1 and contains the point A .Segment AB is tangent to the circle at A and /_AOB=theta. If point C lies on OA and BC bisects the angle ABO then OC equals

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

In figure-3, PQ is tangent to the circle with centre at O, at the point B. if angleAOB=100^(@) , then angleABP is equal to

In the given, figure , O is the centre of the circle and AD is a tangent to the circle at.A if angle CAD =55^@ and angle ADC=25^@ , then find angle ABO .

PA and PB are two tangents to a circle with centre O, from a point P outside the circle . A and B are point P outside the circle . A and B are point on the circle . If angle PAB = 47^(@) , then angle OAB is equal to :

In the figure, O is the centre of a circle and AT is a tangent at point A. The measure of angle BAT is:

The congruent circles with centres Oand O' intersect at two points A and B. Then, angleAOB=angleAO'B .
