To find FH, we should use the Segment Addition Postulate. This postulate tells us that, if we have a point between two points, we can add the lengths of the two smaller segments to find the longer segment length. In our case, G is between F and H, so we can get the length FH by adding FG and GH.
FH = FG + GH
From the diagram, we know that the length FG is 8 and the length GH is 14. Now, we can use this to calculate FH.
