Answer:
KJ = 15
Explanation:
Point K is the centroid of the triangle, it is the point where all the medians intercept. The distance from the centroid to the midpoint of one side is 1/3 of the length of the median. So, we can calculate the length of KJ as follows
[tex]\begin{gathered} KJ=\frac{1}{3}(FJ) \\ \\ KJ=\frac{1}{3}(45) \\ \\ KJ=15 \end{gathered}[/tex]
Therefore, the answer is
KJ = 15
