= ![x^{9}](https://tex.z-dn.net/?f=x%5E%7B9%7D)
6). ![\frac{1}{x^{-2}}=\frac{1}{\frac{1}{x^2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%5E%7B-2%7D%7D%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7Bx%5E2%7D%20%7D)
= x²
7). ![x^{-6}=\frac{1}{x^6}](https://tex.z-dn.net/?f=x%5E%7B-6%7D%3D%5Cfrac%7B1%7D%7Bx%5E6%7D)
8). ![\frac{1}{x^{-7}}=\frac{1}{\frac{1}{x^7} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%5E%7B-7%7D%7D%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B1%7D%7Bx%5E7%7D%20%7D)

Answer:
900 degrees
Step-by-step explanation:
This question is asking you to figure out what all the angles in the shape add up to. There is actually a formula for this: a function of the number of sides that a polygon has.
> Memorize this formula if you will need to do these kinds of problems for your tests/quizzes!
(n - 2) * 180
Since this polygon has 7 sides, we substitute n = 7 into the formula, and solve.
(7 - 2) * 180
5 * 180 = 900
The sum of the interior angles of the polygon shown is 900 degrees.
