Step-by-step explanation:

The sum of arcs around a circle is 360°. This means ...

110° +128° +c° = 360°

c° = 122° . . . . . . . . . . . . . subtract 238°

An inscribed angle in a circle has half the measure of the arc it subtends.

a° = 1/2c° = 1/2(122°) = 61°

The other angles in the diagram are ...

b° = 1/2(110°) = 55°

d° = 1/2(128°) = 64°
