Answer:
c. 12x; 111 cm
Step-by-step explanation:
The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

and if we substitute x = 9.25 cm, we find

18+8/4x2
18+8/8
18+1

Answer:
Seeing that we have a shared hypotenuse and two sides that are congruent, the theorem that we can use is the HL Theorem.
