A chord of a circle is equal to its radius. The angle subtended by this chord at a point on the circumference is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 30∘
Length of chord = Length of radius

Equilateral triangle is formed
Angle at the centre = 60∘
Angle subtended by chord at centre = 2 × Angle subtented by chord at the circumferece of circle
Hence,
Angle subtented by chord at the circumferece of circle = 30∘
