Answer 2

The measure of angle ADB is 130°.

Step-by-step explanation:

Given information: O is the centre of the circle.angle AOB=100° .

We need to find the measure of angle ADB.

Major angle AOB = 360° - Minor angle AOB

$Major(\angle AOB)=360-100=260$

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.

$\angle ADB=\dfrac{1}{2}\times Major(\angle AOB)$

$\angle ADB=\dfrac{1}{2}\times 260$

$\angle ADB=130$

Therefore, the measure of angle ADB is 130°.
