Need on the question (20 points) you : d

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

We can see that is an central angle, meaning that . Essentially, the measure of the central angle () is the same as the measure of the arc () of which it relates to. Since we figured out that , we can also say . is an inscribed angle, meaning that . Essentially, the measure of is equal to one-half of the measure of .

Using this information, we can say that . Thus,
