I'm not exactly sure what kind of answer you are looking for but angle L would also be 72 degrees. This is because 36 (K) + 72 (J) = 108 and a triangle's angles must add up to 180 so 180 - 108 = 72 (L) . This also makes sense because it is an isosceles triangle so two of the angles must be the same because two of the sides are the same length.
