A, B and C are three points on a circle whose centre is O. If angle BOC is equal to 124°, then what is the value (in degrees) of angle BAC ?
Answer & explanation
Correct answer: option 2
We have a concept = The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.
So the angle BAC = \(\frac{124}{2}\) = 62o
