Given:

In circle D, the measure of angle ADC is 108 degrees.

To find:

The measure of angle ABC.

Solution:

Central angle theorem: According to this theorem, the measure of central angle of an arc is twice of the measure of inscribed angle on that arc.

Using the Central angle theorem, we get

m\angle ADC=2\times m\angle ABC

108^\circ=2\times m\angle ABC

\dfrac{108^\circ}{2}= m\angle ABC

54^\circ= m\angle ABC

Therefore, the measure of angle ABC is 54 degrees.
