Answer:
Step-by-step explanation:
1. Draw a figure as the one attached.
2. Point M, the centroid, is the intersection point of the medians.
3. One of the most important properties of M is that it divides any of the medians, in the ratio 2:1, where the larger, is the segment from M to the Vertices.
4. So BM:MQ= 2:1
9x=2(5x-1)
9x=10x-2
x=2 (units)
BQ=BM+MQ=9*2+(5*2-1)=18+10-1=28-1=27 (units)
