c
23,13,13
d
43,23,0
detailed solution
Correct option is D
Given areD,E,F midpoints of the sides of the triangle ABC, so that the centroid of the triangle ABC and the centroid of the triangle DEFare coincident. Hence, the centroid of the triangle DEFis 2+2+03,1+0+13,0+0+03=43,23,0Therefore, the centroid of the triangle ABC is 43,23,0Talk to our academic expert!
