In the figure, angle ABC = 65o and angle ACB = 58o, the measure of angle BDC is
90o
45o
68o
57o
In the figure, O is the centre of the circle and ∠BDC=42o. The measure of ∠ACB is
In the given figure, AC = AD = CD = BD. Then the measure of angle ABC is
If in the following figure, AC = CD, AD = BD and ∠C=58∘, then the measure of angle CAB is
