Answer:
k + h
Step-by-step explanation:
Given that;
The base of a parallelogram is on the x-axis, i.e., it is on the horizontal axis.
The origin (0,0) is located to the left endpoint of the base. This is followed by (k,0) on that same horizontal baseline, now the length of the upper base must be equal to the length of the lower base, from the (k,0) endpoint, the vertical slant line leading to the upper base endpoint is (h,j).
Therefore, the x-coordinate of the fourth vertex will be k unit distant from h.
i.e k+h.
