Answer:
BG = 5
GE = 10
Explanation:
The centroid of a triangle is the point of intersection of its three medians, and it divides each median into two segments, with the ratio of 2 : 1.
As G is the centroid of triangle ACE, and BE is the median, then:

Given the length of BE is 15, we can use the given ratio to find the lengths of BG and GE.
Let x be the common multiplier. Therefore:




Now that we have the value of x, we can find the lengths of BG and GE:


Therefore:
