Question

A chord of a Circle is equal to the
radius of the circle, find the angle
Subtended by the chord at a point
on the minor arc.

​

Answer 1

Answer:

The chord of the circle being the same as the radius of the circlel, the chord subtends an angle of 60 deg at the centre of the circle. The reflex angle at the centre = 360–60 = 300 deg. Hence the chord subtends an angle of 150 deg at any point on the minor arc.

Answer 2

Answer:

30 degree

Step-by-step explanation:

we can solve this by using the formula ÷

the angle subtended by the arc at the centre of the circle is double the angle subtended by it at any other point

So when we join the ends of the chord to the centre then an equilateral triangle is formed

So so the angle at the centre is 60 degree

using the above formula the angle subtended by it at any other point is half of 60 degree which is 30 degree
