Answer:
Scale factor of 1.6.
Step-by-step explanation:
The triangle is dilated and the images is an enlargement of the pre-image. This means all angles of the triangles are congruent and these form similar triangles. Because they are similar triangles which have been dilated, they have a common ratio known as the scale factor between their side lengths. The scale factor here is 1.6 and can be found by using the ratio 0.8/0.5 = 1.6.
