In the figure, angle ABC = 65o and angle ACB = 58o, the measure of angle BDC is
57o
45o
68o
90o
In the figure, O is the centre of the circle and ∠BDC=42o. The measure of ∠ACB is
In the given figure, ∠ BAD = 65o, ∠ ABD = 70o and ∠ BDC = 45o, Find :
(i) ∠ BCD
(ii) ∠ ACB
Hence, show that AC is a diameter.
