Answer:
C) 8cm
Step-by-step explanation:
according to mid point theorem
that “The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”
so
AD=BD
&
AE =CE
then
DE = BC/2
SO ,
BC = 2DE
BC= 2(4)
BC = 8 cm.
