Possible Answers:

Wrong Answer 2: y = 297.0 , x = 243.0

Wrong Answer 4: y = 117.0 , x = 63.0

Wrong Answer 3: y = 117.0 , x = 63.0

Wrong Answer 1: y = 243.0 , x = 297.0

Correct Answer: y = 63.0 , x = 117.0

Correct answer:

Correct Answer: y = 63.0 , x = 117.0

Explanation:

Explanation

INSERT PICTURE HERE

Since this polygon is inscribed within a circle, we know a few things.

The first thing we know is that the sum of all the interior angles must equal 360^{\circ}.

The last thing we know, the most important one is all opposite angles must equal 180^{\circ}.

Now we need to set up equations to solve for \uptext{x}, and \uptext{y}.

180 = y + 117.0

180 = x + 63.0

Now let's solve for \uptext{x}, and \uptext{y}.

y = 63.0

x = 117.0
