GB is 15 units
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The Centroid is a point of triangle where all 3 medians intersect
In this problem point G is the centroid of the triangle FDE
FA, EB and DC are medians of the triangle FDE.
Remember that centroid divides the median in 2:1
FA is a is median so FG:GA=2:1.
Find the value of x
Find the value of GB
GB=2x+3
substitute the value of x
