Points L,M and N are collinear.M is between L and N. You are given LM=13 and LN=20.Find the length of MN

Answer :

ANSWER

MN = 7

EXPLANATION

Let's draw a diagram first:

Since all the points are collinear we can use the segment addition postulate:

[tex]LM+MN=LN[/tex]

Replacing with the values we know:

[tex]13+MN=20[/tex]

And solving for MN:

[tex]MN=20-13=7[/tex]

We have that the length of segment MN is 7.
