Question

Help please :) ! The dashed triangle is the image of the pre-image solid triangle. What is the scale factor used to create the dilation? Enter your answer in the box.

Answer 1

Let

x---------> measure of the base of the triangle of the image

y---------> measure of the base of the triangle of the pre-image

sf-------> the scale factor

we know that

the scale factor is equal to

`sf=(x)/(y)`

in this problem we have

`x=6\ units\\y=3\ units`

Find the scale factor

substitute the values of x and y in the formula above

`sf=(6)/(3)=2`

therefore

the answer is

the scale factor is equal to
`2`
