<u>Answer:</u>

The correct answer option is B. 72°.

<u>Step-by-step explanation:</u>

A polygon is said to be a regular polygon when all its sides and angles are equal.

So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.

When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.

Therefore, option B is the right choice.

It’s 2/25 because 24 x 1/3/100 and you simplify the complex fraction so it’s 24 x 1/300 now reduce the numbers with the greatest common factor 12 so now it’s 2x1/25 then calculate the product 2/25

Ber [7]
So 16 = 3.6, 10 = 2.3 so 20 = 4.6 then add 16 + 20 to get 36 so 3.6 + 4.6 = 8.2
36 ounces = 8.2 cups

36 = 8.2, 8 = 1.8, 20 = 4.6, 36 + 8 + 20 = 64 ounces so 8.2 + 1.8 + 4.6 = 14.6 cups
64 ounces = 14.6 cups

Total cups = 8.2 + 14.6 = 22.8 cups
