180-this number or 360 because its a circumference
Hi!
To find the semmetry between the nonagon just do this:
360 / 9 = 40
The regular nonagon has rotational symmetry of 40 degrees!

Answer:
Quotient = 3
Step-by-step explanation:
We need to solve the given expression :

It can be done as follows :
As, 
So,

Hence, the required quotient is 3.
Answer/Step-by-step explanation:
Given:
C = right angle = 90°
BC = a = ?
AB = c = 12
AC = b = 9
Required:
a, <A, and <B
Solution:
✔️Find a using Pythagorean Theorem:
a = √(c² - b²)
a = √12² - 9²) = √63
a = 7.93725393 = 8 (nearest whole number)
✔️Find A by applying trigonometric ratio:
Thus,
Reference angle = A
Hypotenuse = 12
Adjacent = 9
Therefore,
m<A = 41° (nearest whole number)
✔️Find B:
m<B = 180 - (90 + 41) (sum of interior angles of triangle)
m<B = 49°
