Answer:
4 rotational symmetries for 5 pointed star.
Step-by-step explanation:
To find : How many rotation symmetries does a five-pointed star have?
Solution :
The number of times a shape can be rotated and look the same within one full 360° rotation is called the order of the rotational symmetry, and the angle at which it can be rotated to look the same is called the angle of rotation.
Yes, a 5-point star has rotational symmetry.
A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.
The number of rotation is given by,
Therefore, 4 rotational symmetries for 5 pointed star.

Answer:
Step-by-step explanation:
First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division
Then, you have
Subtract both sides by a squared
DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition
From that you get
Finally, divide both sides by 3.
You get
