Answer
$ML = \frac{5}{2}$
Work Step by Step
If the two legs of a triangle are congruent, then that triangle is an isosceles triangle. Since $\angle JKM$ and $\angle LKM$ are congruent, that means that $\overline{KM}$ bisects $\overline{JL}$. This means that both $\overline{MJ}$ and $\overline{ML}$ are the same length and are each half of the length of $\overline{JL}$.
Let's set up that equation to find the length of $ML$. Let $x$ equal the length of either $ML$ or $MJ$.
$2x = 5$
Divide each side by $2$ to solve for $x$:
$x = \frac{5}{2}$
$ML = \frac{5}{2}$
