Question

(PLEASE TELL ME HOW TO SOLVE IT DON'T JUST DO IT FOR ME...) How many sides does an unnamed polygon have if the sum of the measures of the interior angles is 2340 degrees?

Answer 1

No one is just going to do your homework for you someone is going to give an explanation.

Answer 2

(n-2)180=sum of the interior angles.
Where n=number of angles of a regular polygon.
We know that the sum of the interior angles is 2340
so
(n-2)180=2340 divide both sides by 180 and get
n-2=13 add 2 to both sides and get n=15 Therefore, this polygon has 15 sides.

Answer 3

I know your just copied that off a website.....that doesn't help me because I already looks at that site and I don't know where you're getting these numbers so.....

Answer 4

HaHaHa great deduction. Well you have the answer you wanted right? lol I know I couldn't answer it with my own brain I'm only in 9th grade.

Answer 5

And I'm in 7th your point ...?

Answer 6

Answer 7

Well whatever cause I just wanted to know how to solve and I still don't get it so whatever

Answer 8

My point is Algebra 1 is so hard you forget stuff like this.

Answer 9

Well i'am in 7th and I'm no learning this.

Answer 10

I'm in Pre Algebra

Answer 11

(not) i mean

Answer 12

oh ok

Answer 13

Nice pre-algebra is sooo not hard at all.

Answer 14

I know but many just hate it in my class btw this is how my class looks

Answer 15

ok

Answer 16

7th grade isn't that hard either.

Answer 17

Answer 22

yep XD he doesn't like that.

Answer 23

idk

Answer 24

lol CAUSE IT'S BEEN 2 YEARS!!!!

Answer 25

\(\bf \textit{sum of interior angles of a polygon}=180({\color{red}{ n}}-2)\qquad {\color{red}{ n}}=\textit{number of sides}
\\ \quad \\
thus\qquad 2340=180({\color{red}{ n}}-2)\)

solve for "n", to get the number of sides in the polygon

Answer 26

I don't get where you got the # 180 and the # 2

Answer 27

It's just the formula.

Answer 28

ok

Answer 30

Thank you jdoe0001

Answer 31

The formula for the sum of the interior angles of a shape with n sides is:
180 * (n-2) = S

Substitute in 2340 for S and solve for n:
180 * (n-2) = 2340

Divide both sides by 180:
(n-2) = 13

Add 2 to both sides:
n = 15

The polygon has 15 sides

Answer 32

hope this helped :)
