The answer is C. This is because a equilateral triangle's sides are all equal, meaning any side divided by another has a ratio of 1. That means that you can use dilations to change a triangle into any length and then move them onto each other.

Answer:
z = 8.544[cos(20.6) + isin(20.6)}
Step-by-step explanation:
Given
8 + 3i
Required
Rewrite in trigonometric form.
The trigonometric form of a complex equation is
z = r[cosθ + isinθ]
Let a = 3 and b = 8
Where
r is calculated by
r² = b² + a²
And
θ is calculated by
θ = arctan(a/b)
Substituting 3 for a and 8 for b
r² = a² + b² becomes
r² = 3² + 8²
r² = 9 + 64
r² = 73
√r² = √73
r = √73
r = 8.544
Calculating θ
θ = arctan(a/b) becomes
θ = arctan(3/8)
θ = arctan(0.375)
θ = 20.556°
θ = 20.6 --- Approximated
Hence, z = r[cosθ + isinθ] becomes
z = 8.544[cos(20.6) + isin(20.6)}
Let, initial side is a.
When side is n times long, new side na.
Initial volume, 
Final volume, 
Change in volume, 
For, n = 2 :
n = 3 :
n = 10 :
Hence, this is the required solution.
