The centroid

The centroid of a triangle ABC is at the point (3,3,3). If the coordinates of A and B are (3, –5, 7) and (–1, 7, – 6) respectively, find the coordinates of the point C.

Correct answer:

x =  1
y =  1
z =  2

Step-by-step explanation:

O=(3,3,3) A=(3,5,7) B=(1,7,6)  O = (A+B+C)  x=OxAxBx=33(1)=1
y=OyAyBy=3(5)7=1
z=OzAzBz=37(6)=2
