Ascale factor of (a. 0.125 or b. 8) was applied to the first triangle to the get the resulting image. this scale factor is an enlargement? or a reduction?

Part A) The scale factor is equal to

Part B) Is an enlargement

Step-by-step explanation:

we know that

The scale factor is equal to divide the corresponding side of the resulting triangle by the corresponding side of the first triangle

Let

z----> the scale factor

x------> the corresponding side of the resulting triangle

y-----> the corresponding side of the first triangle

so

we have

substitute

Remember that

If the scale factor is greater than one------> is an enlargement

If the scale factor is less than one------> is a reduction

In this problem

-------> is an enlargement

answer: it's d
