The diagram shows an inscribed angle $$\angle ABC$$. The value 76 degrees is shown as the measure of the arc AC.
The relationship between an inscribed angle and its intercepted arc is:
$$\angle ABC = \frac{1}{2} \times \text{measure of arc } AC$$
Given that the measure of arc AC is 76 degrees:
$$\angle ABC = \frac{1}{2} \times 76^\circ = 38^\circ$$.
