In figure, AB is a chord of the circle and AOC is its diameter such that `angleACB=50^(@)`. If AT is the tangent to the circle at the point A, then `angleBAT` is equal to

In figure, AB is a chord of the circle and AOC is the diameter such that angleACB=50^(@) . If AT is the tangent to the circle at the point A, then angleBAT is equal to : (a) 45^(@) , (b) 60^(@) , (c) 50^(@) , (d) 55^(@)

In the given figure A,B is a chord of the circle and AOC is its diameter ,such that angleACB=50^(@) .If AT is the tangent to the circle at the point A, then angleBAT is equal to :

In Fig RQ is a chord of the circle and POQ is its diameter such that angle RPQ = 30^@ . If QT is the tangent to the circle at the point Q them find angleRQT .

AB is a diameter of a circle and AC is its chord such that angleBAC=30^(@) . If the tengent at C intersects AB extended at D, then BC=BD.

In fig AB is chord of a circle with centre O and AP is the tangent at A such that angleBAP = 75^@ find angleACB

In the figure , point P is the centre of the circle and AB is the diameter . The co-ordinates of A are

In the figure, AB is the diameter of the circle. If angle AOC = 135^(@) then find the angle CDB .

In the figure, O is the centre of the circle . Seg AB is the diameter at the point C on the circle the tangent CD is drawn. Line BD is a tangent to the circle at point B. Show that seg OD || chord AC.
