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 °

the correct answer is the second option

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
