Point E is on line segment DF. Given DE<br> EF.<br> 6 and DF =9, determine the length EF
nlexa [21]

Answer:

<h2>3</h2>

Step-by-step explanation:

Given parameter

DE = 6

DF = 9

Required

EF

Substituting the given parameter into the expression above to get the required will be;

DE+EF = DF.

EF = DF-DE

EF = 9-6

EF = 3

Hence the length of EF is equivalent to 3
