Hello Sir,

This question doesn't mention where O is/doesn't indicate where these points are with respect to O's position. I could draw n no of circles and assume them to be O as the question stem fails to provide some association between O and the given line segments. Please let me know if i'm missing something.

Thanks.

A circle is denoted by its centre. So point O is the centre of this circle.

I understand the denotation sir however no information has been given in the question as to where this center lies(O) or if any of the points mentioned in the question are part of this circle. The intersection of those two chords is denoted by X so i'm not sure where to even start in this problem. Is there a simple diagram which can demystify this confusion?
