Question

A chord of a circle is equal to the radius of the circle. (Fig.1)
Then the angle subtended at the circumference on the major arc is.Please don't write irrelevant answer

Answer 1

30°

Step-by-step explanation:

As the chord is equal to the radius

therefore, OAB is an equilateral triangle

so, the angle AOB = 60° .

there is a theorem : THE ANGLE SUBTENDEDBY AN ARC OF A CIRCLE AT THE CENTRE IS DOUBLE THE ANGLE SUBTENDED BY IT AT ANY POINT ON THE REMAINING PART OF THE CIRCLE .

SO, if angle AOB =60°

Then, angle APB =30°

Hope this is helpful !
