To determine the length of stack FH when F is the midpoint of stack GH, you can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint (F) between two points (G and H) can be found by taking the average of their respective coordinates.
In this case, let's assume that G and H are points on a one-dimensional line (a stack), and we're interested in finding the length of FH.
If F is the midpoint, it means that F is equidistant from G and H. So, you can use the following formula to find the length of FH:
Length of FH = |H - F| = |F - G|
Since F is the midpoint, it's equidistant from both G and H, and the length of FH is equal to the length of FG.
So, to find the length of FH, you need to know the coordinates of G and H on the stack. Once you have those coordinates, you can calculate the length by subtracting the coordinate of G from the coordinate of H (or vice versa) and taking the absolute value.
