Answer:
The scale factor is 2.5 to 1 which is 1/2.5
Step-by-step explanation:
Here, we want to get the scale factor in the given image
The scale factor we want to get is from the big to the small triangle
To get this, we find the ratio of the sides which are the same
Thus, we have ;
7/2.8 = 2.5
So the scale factor in this case is 2.5 to 1
