1. What are the coordinates of Z?

Answer:
A z coordinate is the third-dimensional coordinate in a volume pixel , or voxel . Together with x and y coordinates , the z coordinate defines a location in a three-dimensional space.
Step-by-step explanation:
Answer:
z coordinate =0 since this is xy plane.
Step-by-step explanation:
Given is a planar graph which contains a parallelogram.
The parallelogram is lying on xy plane.
The parallelogram is a planar figure drawn on xy plane.
We have in 3 dimensional cartesian system of coorindates in the xy plane z=0
Hence we have z coordinate =0
