Question

O is the center of the circle angle AOB=100 find angle ADB​

Answer 1

Explanation:

angle AOB=100° .

We need to find the measure of angle ADB.

According to the central angle theorem the central angle generated by two points on a circle is twice the inscribed angle subtended by those points.

Therefore, the measure of angle ADB is 130°.

Answer 2

2×angle ADB=AOB

angle ADB=100/2

angleADB=50
