Here, the AB is equal to the Radius. So if we draw a triangle with AB as the base and the third vertex as the centre O, we get a triangle AOB. Now Angle x and Angle AOB is made by the same base AB. Now we know angle at the centre of the circle is twice the angle at the circumference. or, angle AOB ...

since AB is equal to the radius of the circle triangle OAB is equilateral. hence angle AOB is 60
x=1/2*angle AOB=30
I understand the equilateral part. But, how is x=1/2*angle AOB=30. Which property is this? Yes, the answer is B
