Final answer:
In an isosceles triangle KLM with equal angles at K and M, and knowing that ML = 18 and MK = 6, the length of KL is also 6.
Step-by-step explanation:
In the triangle KLM, given that angle K is equal to angle M, ML = 18, and MK = 6, we need to find the length of KL. Since K = M, the triangle KLM is isosceles with KL equal to KM. Therefore, we know that the length of KL is also 6 units, because in an isosceles triangle, the sides opposite to the equal angles are equal in length. The solution to finding the length of KL in this situation is straightforward once acknowledging the property of isosceles triangles.
