Question

11. Find x, y, and z. El Br 120 6 32 C D is the centroid of AABC.

Answer 1

`\begin{gathered} 9z+6=24 \\ 9z=24-6=18 \\ z=2 \end{gathered}`

Having that z=2 we get

`\begin{gathered} (24)/(12)=(24)/(6x) \\ 2=(4)/(x)\rightarrow x=2 \end{gathered}`

And we have that

`(24)/(12)=(32)/(8y)=(4)/(y)\rightarrow y=2`

so z=x=y=2
