We are told that MN is a midsegment of △ JKL. This means that M is a midpoint of JK and N is a midpoint of JL.
According to the Triangle Midsegment Theorem, if a segment joins the midpoints of two sides of a triangle, then it is half as long as the third side. This allows us to relate the lengths of MN and KL.
MN = 1/2 KL
Let's substitute the given lengths and solve the equation.
