Answer:
Option (2)
Step-by-step explanation:
HL theorem for congruence states that if hypotenuse and one leg of one right triangle are congruent to the corresponding sides of the of the right triangle, both the triangles will be congruent.
By this theorem,
ΔACB ≅ ΔFED
If AB ≅ DF [Hypotenuse]
AC ≅ EF [Leg]
By these properties,
AC = EF = 12
Or BC = DF = 28
Therefore, Option (2) will be the correct option.
The answer is x=9 and x=3
