Answer:
A
Explanation:
EL is a median of Δ DEF
the median is a segment that goes from one of the triangle's vertices to the midpoint of the opposite side.
the 3 medians of a triangle intersect at its centroid
on each median , the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint , then
EM = 2 ML , that is
6 = 2 ML ( divide both sides by 2 )
3 = ML
Then
EL = EM + ML = 6 + 3 = 9
