Answer:
see the explanation
The graph in the attached figure
Step-by-step explanation:
we know that
In the right triangle LMN
Applying the Pythagorean Theorem
[tex]MN^2=LM^2+LN^2[/tex]
we have
[tex]MN=5a\ units\\LM=3a\ units[/tex]
substitute
[tex](5a)^2=(3a)^2+LN^2[/tex]
[tex]LN^2=25a^2+-9a^2[/tex]
[tex]LN^2=16a^2[/tex]
[tex]LN=4a\ units[/tex]
