Question

Can someone please explain how to do this?
If the sum of the measures of the interior angles of a convex polygon is 2880°, how many sides does the polygon have?

Answer 1

I don't remember the method.

Answer 2

im here

Answer 3

(n-1)180 = 2880, Solve for n.

Answer 4

Thanks! Can you give me the plain formula too? @ajspeller

Answer 5

n is the number of sides

Answer 6

measure of each angle is found by (n-1)180 divided by n
measure of the sum of the interior angles is found by (n-1)180

Answer 7

Not sure what you mean by the plain formulas.

Answer 8

I mean like the distance formula, where you plug in the values for any problem. So what is the formula here?

Answer 9

(n-1)180

Answer 10

can i have a medal now

Answer 11

Hey I made a mistake .. its (n-2)180 ... NOT (n-1)180.. sorry
