AF = 10x=3

EF = 2x+5

EB = 4x+3

This is for median of triangles.

**Reiny**, Tuesday, February 21, 2012 at 5:23pmYou have probably learned that the centroid divides a median in the ratio of 2:1, with the longer side towards the vertex.

I will assume that the median is AF, and you meant

AF = 10x + 3

so AF : EF = 2:1

(10x+3)/(2x+5) = 2/1

crossmultiply

10x + 3 = 4x + 10

6x = 7

x = 7/6

Not enough information to find DB.

Was the triangle isosceles or equilateral?
