here the other angle is given as 120°. then the other angle will be 60° by linear pair.
now join both the points on the circumference and observe that we can apply the theorem which states that 'the angle made on the centre of the circle by a chord is double the angle subtended on any point on circumference.'

Answer:
(D) 30°
Explanation:
here the other angle is given as 120°. then the other angle will be 60° by linear pair.
now join both the points on the circumference and observe that we can apply the theorem which states that 'the angle made on the centre of the circle by a chord is double the angle subtended on any point on circumference.'
So, now
2x=60°
x=30°
