i cant see that well. please take a clear photo ;-;
Step-by-step explanation:
Do you understand trigonometry ? (sine, cosine, tangent)
Answer:
The center of dilation of ABCD to EFGH is (0, 0), and the scale factor is 4/3
A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.
Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm
Area of each triangle = 9/2(16.79) = 75.57 cm^2
Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2
