Question

can u please help me?
What is the measure of one angle of a regular polygon with nine sides?

Answer 1

firstly You must not forget the formula that is :

(n-1)180 = sum of all the interior angles of the regular polygon,
where n = no. of sides
This formula only works when the polygon is regular.
now n = 9
(9-1) 180
8*180
1440 degree /9 = one interior angle's measure
160 degree

Answer 2

360/9 = exterior angle

Answer 3

i thought the formula is (n-2)180

Answer 4

Just subtract the answer to what I put from 180.

Answer 5

No need to mess about with the formula (which, u r right is n-2).

Answer 6

360/9 = 40 --->180-40= 140.

Answer 7

Yes?No?

Answer 8

yes
