Step-by-step explanation:
In given figure ,O is the center of circle .∠AOB=100
0
Then external ∠AOB=360
0
−100
0
=260
0
We know that the angle subtended by an arc at the center of a circle is twice
the angle subtended by the same arc at any other point on the remaining part of the circle.
Arc ∠ADB=
2
1
Ex∠AOB=
2
