Answer:
GH = 19
Explanation:
FH = 32
FG = 13
FH is the total length of the line. FG is only equal to a segment.
So you're going to subtract the total length from the segment.
It should look like this
![32 - 13 = GH](https://img.qammunity.org/2023/formulas/mathematics/college/nk4tw2jlhp88j45a2v4ks6gj5p6sx3o739.png)
When you subtract 32 from 13, you'll get 19, which is equal to the length of GH.
