Question

. In figure, BC is a diameter of the circle
BAO = 60°. Then, ADC is equal to
(a) 30
(b) 45
(c) 60
D) 120
​

Answer 1

Answer:

itz option (c)

In ΔAOB,

∠OBA = ∠BAO

[angles opposite to equal sides are equal]

∠OBA = 60° [∴ ∠BAO = 60°, given]

∠ABC=∠ADC

[angles in the same segment AC are equal]

∠ADC = 60°

hope this will helps u...
