Given:
A 7-sides regular polygon.
To find:
The sum of the interior angles of the given regular polygon.
Solution:
The formula for the sum of the interior angles of a regular polygon is:
![Sum=180^\circ(n-2)](https://tex.z-dn.net/?f=Sum%3D180%5E%5Ccirc%28n-2%29)
Where, n is the number of sides of the regular polygon.
The given regular polygon has 7 sides. Putting
in the above formula, we get
![Sum=180^\circ(7-2)](https://tex.z-dn.net/?f=Sum%3D180%5E%5Ccirc%287-2%29)
![Sum=180^\circ(5)](https://tex.z-dn.net/?f=Sum%3D180%5E%5Ccirc%285%29)
![Sum=900^\circ](https://tex.z-dn.net/?f=Sum%3D900%5E%5Ccirc)
Therefore, the sum of the interior angles of the given regular polygon is 900 degrees.

Answer:
9
Step-by-step explanation:
You divide 22.5 by 2.5, which is equal to 9.
9 and 2/4 can be written as 9.5 in decimals. We usually round 5 up, so we would round it to 10.
if it was 9.4 we would round it down to 9.
Answer:
x = 3
Step-by-step explanation:
<em>Given </em>
<em>4</em><em>(</em><em>5</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em><em> </em><em>)</em><em> </em><em>=</em><em> </em><em>4</em><em>8</em>
<em>5x </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>4</em><em>8</em><em> </em><em>/</em><em> </em><em>4</em>
<em>5x </em><em>-</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>1</em><em>2</em>
<em>5x </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>+</em><em> </em><em>3</em>
<em>5x </em><em>=</em><em> </em><em>1</em><em>5</em>
<em>x </em><em>=</em><em> </em><em>1</em><em>5</em><em> </em><em>/</em><em> </em><em>5</em>
<em>x </em><em>=</em><em> </em><em>3</em>
<em>Therefore </em><em>x </em><em>=</em><em> </em><em>3</em>
