Answer:
   x = 4
Step-by-step explanation:
Corresponding segments of similar triangles are proportional. Here, the similar triangles are ...
   ΔABC ~ ΔADE
so the relationship between the sides is ...
   BC/BA = DE/DA . . . . . . we put the unknown value in the numerator
   x/4 = 12/(4+8)
   x = 4(1) = 4
The length of side x is 4.
