In the figure, A,B,E,C and D are the points on the circle. If `AB=BE` and `/_ACB =30^(@)` , then find `/_ADE`.

In the following figure, AB is an arc of the circle, C and D are the points on the circle. If angle ACB=30^@ , Find angle ADB .

In the circle with centre O and A,B,C are the points on the circle, angle AOB = 60^(@) . Find angle ACB

In the adjoining figure 'O' is the center of the circle AB=BCm/_AOD=x and m/_ACB=y then find (x)/(y) .

In the above figure, O is the centre of the circle AB,AD and CD are the chords . If /_ ADC=130^(@) then fid /_ ACB .
