Answer:

A

Explanation:

The ratios of corresponding sides are equal, that is

(XZ)/(DF) =
(XY)/(DE) , that is

(12)/(8) =
(9)/(x) ( cross- multiply )

12x = 72 ( divide both sides by 12 )

x = 6

x = DE = 6 → A

Answer:

x= 6

Explanation:

You need to set up a proportion

12/8 = 9/x

Then you do Cross Product Property

8*9=72

12*x=12x

12x=72

divide 72 by 12

72/12=6

x=6
