Find the Measure of the Inscribed Angle

Angle ABC is inscribed in a circle as shown.

What is the measure, in degrees, of  ∠ABC ?

---

The measure of an inscribed angle is half the measure of its intercepted arc.

The intercepted arc of ∠ABC  measures 120°.
120 ÷ 2   {took half of the intercepted arc}
= 60   {divided}

∠ABC  = 60°
