Question

What’s the scale factor in the dilation? Help it’s not that hard help me out I give crowns

Answer 1

Answer:

Option (4)

Step-by-step explanation:

From the graph attached,

ΔABC is the preimage and ΔA'B'C' is image of ΔABC when dilated by a scale factor 'k'.

Scale factor 'k' = $\frac{\text{Dimension of image triangle A'B'C'}}{\text{Dimension of preimage triangle ABC}}$

                    'k' = $\frac{A'C'}{AC}$

                        = $\frac{7.5}{3}$

                        = 2.5

                        = $2\frac{1}{2}$

Therefore, Option (4) will be the correct option.
