Using the segment addition postulate, find the length of segment EF.


EG = 17

FG = 12

FIRST ONE - 12
SECOND ONE- 5
THRIDS ONE- 29

Answer 1

(b) EF = 5

Explanation:

Given point F lies on segment EG, you want to find EF when FG = 12 and EG = 17.

Segment addition

The segment addition postulate tells you the whole is the sum of the parts. That is ...

EF +FG = EG

EF +12 = 17 . . . . . substitute given lengths

Subtracting 12 from both sides of the equation, we have ...

EF = 5
