Question

what is the angle at a center of a circle if the subtending chord is equal to two thirds of the radius?

Answer 1

Answer:

Congruent arcs (or equal arcs) of a circle subtend equal angles at the centre. Therefore, the angle subtended by a chord of a circle at its centre is equal to the angle subtended by the corresponding (minor) arc at the centre.

Answer 2

The Angle Substended by the Chord at the Point on the Major Arc if the Chord & the Radius is of equal length is equal to 30°.
