Best ResponseYou've already chosen the best response.0I think so? Something about a centroid? This is a question that I posted for my brother because he doesn't know how to do this. Everything should be even in the drawing but i'm not an expert artist or anything lol.

Best ResponseYou've already chosen the best response.1if that's the case, then AE, GC, and BF are medians they all intersect at the centroid The distance from any vertex to the centroid is always twice as large as the distance from the centroid to the midpoint on the opposite segment (along the same median)

Best ResponseYou've already chosen the best response.1what does this mean? it means that we can say BD = 2k DF = k for some number k dw:1358122081547:dw

Best ResponseYou've already chosen the best response.1So BD = 2*DF 4x+5 = 2*9x solve for x, then use this to find BD and DF Your last step is to use them to find BF = BD + DF
