1 answer:
Answer:
The approximate scale factor dilating from the blue image to the red image is 3.5
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor
see the attached figure to better understand the problem
Let
z------> the scale factor
![z=\frac{A'B'}{AB}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BA%27B%27%7D%7BAB%7D)
Observing the attached figure
AB=x
A'B'=3.5x
substitute
![z=\frac{3.5x}{x}=3.5](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B3.5x%7D%7Bx%7D%3D3.5)

Answer:
32 +x+x=180(Sum of angles of a triangle)
32+2x=180
2x=180-32
2x=148
x=148/2
Therefore,X=74
