Trust me its correct

Answer 2

Answer:

Three-fourths

Step-by-step explanation:

Triangle XYZ

$XY=10\\ZY=12\\ZX=8$

Triangle X'Y'Z'

$X'Y'=7.5\\Z'Y'=9\\Z'X'=6$

To find the factor of dilation, we just need to divide the sides of the prime figure with the sides of the original figure.

$\frac{10}{7.5}= 1.333333333..\\\frac{12}{9}=1.333333...\\ \frac{8}{6}=1.3333333....$

Notice that 1.333333.... is equivalent to 4/3, but the factor of dilation is from the smaller figure to the bigger figure. That means it's the opposite: 3/4.

Therefore, the factor of dilation is three-fourths.
