Answer:

x = 6 and DF = 3*6-3 = 15

Explanation:

Given triangles are similar and their side lengths are proportional

the similarity ratio for this pair is 4/8 = 1/2

the length of DF:

(7.5)/(3x - 3) = 1/2 cross multiply expressions

3x - 3 = 15 add 3 to both sides

3x = 18 divide both sides by 2

x = 6 and DF = 3*6-3 = 15
