Question

in the adjoining figure if O is the center of circumcircle of angle ABC and angle AOC = 110degree let us write by calculating the value of angleABC.​

Answer 1

Step-by-step explanation:

ABC = 125°

Step-by-step explanation:

Given : ∠ AOC = 110°

To find: ∠ ABC

Now as given

∠ AOC = 110°

Therefore reflex of ∠ AOC is

Reflex ∠AOC = 360°- ∠AOC = 360° - 110°= 250°

Now

As we know :Angle subtended by an arc of a circle at the centre is double the angle subtended by it at any point on remaining part of the circle.

So

2 ∠ABC = Reflex ∠AOC

⇒ 2∠ABC = 250
