In the given figure, 'G' is the centre of the circle. Find the angle ACB when
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 66º
Given that
As we know,
The angle made by an arc at the centre is twice the angle formed by the same arc at the circumference of a circle.
Hence, the angle ACB = the angle AGB/2 = 132º/2 = 66º
