Yes
No it isn't.
1260
It goes: 1260/2 = 630 times
(N - 2)*180 = (9 - 2)*180 = 1260 degrees.
1260/1 or 2520/2 are two examples.
yes 60 times
Suppose the polygon has n sides. Then (n - 2)*180 = 1260 So (n - 2) = 1260/180 = 7 and therefore, n = 7 + 2 = 9
1260 2, 630 2, 2, 315 2, 2, 5, 63 2, 2, 5, 7, 9 2, 2, 5, 7, 3, 3
1,260 multiplied by 2 is 2,520.
2 x 2 x 3 x 3 x 5 x 7 = 1260
30% of 1260= 30% * 1260= 0.3 * 1260= 378
3% of 1260 = 3% * 1260 = 0.03 * 1260 = 37.8
