Answer:
The right answer is 12 degrees of rotation.
Step-by-step explanation:
to resolve this problem, we need to know that we can find the central vertex angle of a polygon with the next formule=
where n is the number of sides of the polygon.
now knowing this we can replace the data in the formule=
x=360/30= 12
12 is the central vertex angle, which is the same as the degree of rotation for a 30 sided polygon
