Question

In the given figure, O is the centre of the circle.
angleAOC + 2 angleABC is​

Answer 1

Answer:

the answer is 2 times the angle ABC

Step-by-step explanation:

By using half angle theorem

Answer 2

Answer:

reflex angle AOC = 2*angle ABC

(angle at centre is twice the angle at other parts)

so, reflex angle AOC + angle AOC

=360 degree

so indirectly, angle AOC + 2 angle ABC=360 degree
