Question

Triangle D has been dilated to create triangle D′. Use the image to answer the question. image of a triangle labeled D with side lengths of 6, 8, 10 and a second triangle labeled D prime with side lengths of 18, 24, 30 Determine the scale factor used. one half 2 3 one third

Answer 1

Answer: 3

Explanation:

I took the quiz so you do not have to!

Answer 2

Dilating a shape will proportionately affect its side lengths.

To find the scale factor between the given triangles, take one side on the larger triangle and divide it by the corresponding side on the smaller triangle. I will divide the triangles' top sides (24 and 8).

`\text{scale factor}=(24)/(8) =3`

So, the scale factor used was 3.
