Question

from the figure,find the length of seg BC

Answer 1

Given
AD=DB,AE=EC
IT MEANS D&E ARE MID POINTS
SO,
BY MID POINT THEOREM
DE=1/2BC
2DE=BC
2(3.2)=BC
6.4 CM=BC
HOPE IT HELPS YOU

Answer 2

by bpt theorem

[tex]\frac{AD}{AB} =\frac{DE}{BC} \\\frac{AD}{AB}=\frac{1}{2} \\ SO \\\frac{1}{2} =\frac{3.2}{BC} \\BC=6.4\\[/tex
