Given
The measure of the arc AC is

The measure of the angle ABC is

We need to determine the value of x.
Value of x:
The inscribed angle theorem states that, "the measure of an inscribed angle is half the measure of the intercepted arc".
Applying this theorem, we have;

Substituting the values, we get;


Thus, the value of x is 41°
Therefore, the measure of angle ABC is 41°
