Exercise 16 Page 392

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 19 and the length GH is 7. Now, we can use this to calculate FH.

FH=FG+GH

SubstituteII

FG= 19, GH= 7

FH= 19+ 7

FH=26

The length FH is 26.
