A chord of a circle is equal to its radius of length 9 cm. Find the angle subtended by it in major segment.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 30°.
Given that
Chord length is equal to the radius of a circle = 9cm
hence, the triangle formed by the chord at the center is an equilateral triangle so the angle at the center = 60º
The angle subtended by a chord at the major segment = 60º/2 = 30º
