Please Help Me What Is The Length Of DE class=

Sagot :

Answer:

B

Step-by-step explanation:

The 2 triangles are similar, so the corresponding sides are in proportion, that is

[tex]\frac{DE}{XY}[/tex] = [tex]\frac{FD}{ZX}[/tex] , substitute values

[tex]\frac{DE}{9}[/tex] = [tex]\frac{8}{12}[/tex] ( cross- multiply )

12 DE = 72 ( divide both sides by 12 )

DE = 6 → B
