Question

In the given figure, in a circle with centre 0,
length of chord AB is equal to the radius of
the circle. Find measure of each of the
following
a./_AOBь./_ ACB
​

Answer 1

Answer:

The measure of an angle subtended by an arc at a point on the circle is half of the measure of the angle subtended by the arc at the centre. Thus, the measure of ∠ACB is 30º. Thus, the measure of arc AB is 60º. Thus, the measure of arc ACB is 300º.
