Answer:
D
Step-by-step explanation:
The pentagon has 5 interior angles that add up to 360. To find the angle of rotational symmetry, divide 360 by 5 (you get 72). So if you rotated the shape 72 degrees, it will map onto itself. 72 times 2 is 144, and that's rotating the shape 72 degrees twice, so it will stay the same.
 
        
             
        
        
        
3/5 • 4/5 = 12/25.
This would be the solution to the above question, simply multiply both the numerator and denominator together to get the final answer.
