Question

Given that the triangles below are similar.find the scale factor

Answer 1

The triangles are similar, then scale factor is equal to ratio of corresponding sides of two triangle.

`\begin{gathered} x=(24)/(30) \\ =(4)/(5) \\ =\text{0}.8 \end{gathered}`

Or

`\begin{gathered} x=(32)/(40) \\ =(4)/(5) \\ =0.8 \end{gathered}`

Thus, scale factor for the triangles is 0.8.
