Can you explain how \(\angle ABC\) & \(\angle AOC\) are related?
Can you form an equation for them?
Explain how you arrive at this equation.
Note : \(\angle AOC\) refers to the smaller angle (either acute or obtuse \(\angle\)). For the larger angle (reflex \(\angle\)), it is referred to as "reflex \(\angle AOC\)".
