The first thing that would help you the best is to know the sum of the angles of a nine sided polygon. 

The formula for finding the sum of interior angles for any polygon is (n-2)*180
where "n" is the number of sides.

So, plug in 9 for n.

9-2 = 7
7 * 180 = 1260
Now , subtract all the known interior angles from 1260.
After subtracting all the known interior angles from 1260 you should be left with 100.

This means that the value of x is equal to 100

We know, sum is equal to 1260 in polygon with 9 sides, 
so, 52 + 244 + 144 + 70 + 81 + 272 + 97 + 200 + x = 1260
1160 + x = 1260
x = 100

In short, Your Answer would be 100

Hope this helps!

               6 + 4 ÷ 2

The "order of operations" (which you learned a long time ago
if you're in high school now) says that division should be done
before addition.

So do the division:        4 ÷ 2 = 2

Now you have                6 + 2

Now do the addition:     6 + 2 = 8 .

Write an expression for the sequence of operations described below.
Hatshy [7]

The expression for the sequence of operations described below is d/3 + 5

<h3>Expressions and equations:</h3>

  • Let the unknown value be "d"

  • d divided by 3 is expressed as d/3

Adding 5 to d/3 to get the expression below;

g(d) = d/3 + 5

Hence the expression for the sequence of operations described below is d/3 + 5
