The scale factor would be 2.5. Since the triangles are similar, you can use the Proportionality Theorem to find that 15/6 = 2.5, 10/4 = 2.5, and 20/8 = 2.5. Since the proportions are equal, the scale factor would be 2.5. More specifically, it's a reduction of 2.5. 

Hope this helped! If you need further assistance, comment under this post or message me!

The scaled factors would be 2.5 becuz the triangles are similar, you can use the proportion to find that 15/6 = 2.5 and 10/4 = 2.5, and 20/8 = 2.5. Since the proportions are the same the scale factor would be 2.5.
