| 1. A, B, C, D – the tops of the trapezoid. AB + CD = 26 units. MK is the middle line.
2. A circle can be inscribed in a trapezoid only if the following conditions are met: the sum of the lengths of the opposite sides must be equal to:
BC + AD = AB + CD.
3. MK = (BC + AD) / 2.
4. ВС + АD = 26 units of measurement.
(ВС + АD) / 2 = 13 units.
Therefore, MK = 13 units of measurement.
Answer: MK = 13 units of measurement.
