Question

In the given figure, ‘O’ is the centre of the circle, then the value of y is

A) 45° 

B) 90° 

C) 60° 

D) 30°

Answer 1

Correct option is (B) 90°

If O is the centre of the circle. Then \(\angle y\) is an angle made in a semi-circle.

\(\therefore\) \(\angle y\) = \(90^\circ\)    \((\because\) Angle made in a semi-circle is \(90^\circ)\)

\(\Rightarrow\) y = \(90^\circ\)

Answer 2

Correct option is  B) 90°
