Answer :

Final answer:

The length of segment LM in this geometry problem is 9, based on the properties of midpoints and line segments.

Explanation:

This question is about the geometry, specifically dealing with line segments and their lengths. Let's start with the provided information: L is the midpoint of JM which means JL and LM are equal lengths, and K is the midpoint of JL, which means JK and KL are equal lengths.

Given that JK = 9, we can conclude that KL is also 9 because K is the midpoint of JL. Then, since JKL is half of JM, the length of JM must be 2 times JK (or 2 times KL), therefore, JM = 2 * 9 = 18.

Since L is the midpoint of JM, the lengths of JL and LM are also equal. Therefore, the length LM is half the length of JM, which is 18/2 = 9.
