Use (n - 2) * 180 to find the sum of the measures of the interior angles of the polygon, where n = number of sides.

This polygon has 9 sides so plug in 9 for n.

(9 - 2) * 180 = 1,260

Divide this by the number of sides, 9.

1,260/9 = 140

Now divide this by 2 because x appears to be half of an interior angle (the radius is bisecting the interior angle).

140/2 = 70

x = 70°

The rate of change is -5/4

I find it best to use the Slope formula
M= y2-y1/x2-x1

So we to use need any 2 points on the graph (I used the first 2)
•(0,200) and (80,100)

Now we set up the problem 100-200/80-0
Then you’ll subtract and should get
-100/80
Now you’ll simplify and once you’re done simplifying your answer should be -5/4.

Here is my work. Hope this Helps!
