I'm new too, but I'm pretty sure if you have a question then you ask it, attach a picture if needed, and people might see it and answer.
Answer:
75 feet
Step-by-step explanation:

4x=60 so x would =15
then you multiply 15 by 5 and end up with 75
The answers is -1/3 because of rise over run
* J,K,&L are coplanar
* K is the midpoint of JL
* J,K,&L are collinear
* Jk=KL
