Step-by-step explanation:
Hi!
To find the semmetry between the nonagon just do this:
360 / 9 = 40
The regular nonagon has rotational symmetry of 40 degrees!
Answer:
7/165
Step-by-step explanation:
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242
I think this is what you do. Hope it helps!
