Final answer:

In triangle ABC, the centroid G divides each median in a ratio of 2:1. To find BG and GE, calculate two-thirds and one-third of the length of BE, respectively.

Step-by-step explanation:

In triangle ABC, the centroid G divides each median in a ratio of 2:1. This means that BG is two-thirds of the length of the median BE, and GE is one-third of the length of BE.

Given that BE = 21, we can calculate:

BG = (2/3) * 21 = 14.

GE = (1/3) * 21 = 7.

Therefore, the correct answer is (BG = 14, GE = 7).
