Answer 1

What the person below said very smart

Answer 2

Let's start by knowing what information we are given in the problem and what we can infer.

1. We can see that
   `\angle OAD` is an central angle, meaning that
   `m\angle OAD = m \stackrel \frown{AC}`. Essentially, the measure of the central angle (
   `\angle OAD`) is the same as the measure of the arc (
   `\stackrel \frown{AC}`) of which it relates to. Since we figured out that
   `\angle OAD = 62^(\circ)`, we can also say
   `m \stackrel \frown{AC} = 62^(\circ)`.
2. 
   `\angle ABC` is an inscribed angle, meaning that
   `m\angle ABC = (1)/(2) \,m\stackrel \frown{AC}`. Essentially, the measure of
   `\angle ABC` is equal to one-half of the measure of
   `\stackrel \frown{AC}`.

Using this information, we can say that
`m \angle ABC = (1)/(2) (62^(\circ)) = 31^(\circ)`. Thus,
`\boxed{m \angle ABC = 31^(\circ)}`
