Answer:
BG = 8
EXPLANTAION :
we know that centroid of a triangle divides the median into ratio of 2 : 1 so,
BG : GF = 2 : 1
now, let's take BG as 2x and GF as x
and here, BG + GF = BF
So,
=》2x + x = 12
( because, BF = 12 )
=》3x = 12
=》x = 12 ÷ 3
=》x = 4
hence, x = 4
from here,
=》BG = 2x
=》BG = 2 × 4 = 8
