Angle subtended by an arc at its centre is ‘x°’ then, angle subtended by it at any other point on the circle isA) x°/2B) 2x° C) x° D) 180 – x°

Answer»

Correct option is (A) \(\frac{x^\circ}{2}\)

Angle subtended by an arc at the centre is double then the angle subtended by that arc at any other point on the circumference of the circle.

\(\therefore\) \(x^\circ\) = 2 \(\times\) Angle subtended by arc at any other point on the circle.

\(\therefore\) Required angle = \(\frac{x^\circ}{2}\)

Correct option is  A) x°/2
