@jonjenkins7653 ??

OpenStudy (anonymous):

if z is the centroid, then it means that from Z to A, the distance is (2/3)rds of the total height of the triangle |dw:1383859925917:dw|

@Faith_Rochelle ^_^

OpenStudy (anonymous):

So what formula could I use to figure out what ZY is ?

OpenStudy (anonymous):

@DemolisionWolf

OpenStudy (anonymous):

formula... how about this formula i'll make from looking at the picture I drew: h = (2/3)h + (1/3)h and (2/3)h = AZ = 12 does that help?

OpenStudy (anonymous):

so it is 6 right ?

OpenStudy (anonymous):

yep ^_^ I was just gonna reword my prior response
