Statics - Centroids of Composite Shapes #1 

For right triangles, the centroid is 1/3 the distance from the right angle.

Recall that our reference point is the origin. So the centroid of the triangle is the distance from (0,0) to the centroid of the triangle

It's not, it should be 11. His Xc value is what I got and I used 11 not 12, I think he just wrote it wrong

Aviator 737 No problem

Your coordinate system is key for determining the xbar and ybar values. If you, let’s say, change your coordinate system so that your x and y axis flip directions in this problem, you’d deal with sign changes for xbars and ybars (This also assumes you didn’t translate the origin of your system). The result should be the same if you work it out both ways.
