Question 1133727
<br>
Triangles JNM and MNL are similar triangles.<br>
(1) Use the Pythagorean Theorem to find the length  of JN.  (Or you might recognize the lengths of MN and JM as being part of a Pythagorean triple, which means you won't need to use the Pythagorean Theorem.)<br>
(2) Use the two similar triangles to find the length of NL.<br>
(3) The length you need to find is the sum of the lengths of JN and NL.
