Question

in the figure below, f is between e and g, and g is between f and h. if ef = 7, fg = 5, and eg = 12, find eh.

Explanation:

Step1: Find length of EF

Since $EG = EF+FG$ and $EG = 12$, $FG = 5$, then $EF=EG - FG$.
$EF=12 - 5=7$

Step2: Find length of EH

Since $EH=EF + FH$ and $FH = 7$, $EF = 7$, then $EH=7 + 7$.
$EH = 14$

Answer:

$14$
