For a regular 30 sided polygon what is the degree of rotation

12

Step-by-step explanation:

The interior angle of a regular polygon of "n" sides is calculated with the formula:

(n-2) × 180 ° / n.

(8-2) × 180 ° / 8 = 6 × 180 ° / 8 = 135 °

And that of a square is (4-2) × 180 ° / 4 = 2 × 180 ° / 4 = 90 °

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
