Answer:
The scale factor is 2
Step-by-step explanation:
From the diagram, triangle MNO is the image of triangle RST.
The scale factor is given by:
[tex]k=\frac{Image\; Lenth}{Corresponding \:Object\;Length}[/tex]
This implies that:
[tex]k=\frac{MN}{RS}[/tex]
From the diagram, |MN|=6 and |RS|=3.
We substitute the values to get:
[tex]k=\frac{6}{3}=2[/tex]
Therefore the scale factor is 2
