Question

in the given figure o is the centre of the circle and angle AOC is equals to 120 degrees find angle abc​

Answer 1

Answer:

angle AOC= 360-90-120

angle AOC= 360-210

angle AOC= 150 degrees

m (arc AC)= 150 degrees

Using Inscribed Angle Theorem

m(angle ABC)=0.5*m(arc AC)

m(angle ABC)=0.5*150

angle ABC= 75 degrees
