Question 1
1 / -0

If a chord of a circle is equal to its radius, then the angle subtended by this chord in major segment is

A
90^o

B
60^o

C
45^o

D
30^o

Solution

Since the chord is equal to the radius therefore, it will form an equilateral triangle inside the circlewith the third vertex being the centre of the circle.

So the chord will make an angle of 60⁰ at the centre. As the angle made by the chord at any other point of the circumfrence would be half.

So, we have that angle made at the major segment would be 30⁰.
