3. Прямые m и n параллельны. Найдите $$\angle 2$$, если $$\angle 1 = 48^{\circ}$$, $$\angle 3 = 57^{\circ}$$. Ответ дайте в градусах.

Image contains a diagram with intersecting lines. The question asks to find the angle labeled '2' given angles '1' and '3', and that lines 'm' and 'n' are parallel. However, the provided diagram does not show lines 'm' and 'n' or angles labeled '1', '2', and '3' in a way that allows for a solution. The diagram seems to depict two intersecting lines forming angles, with one angle labeled $$52^{\circ}$$ and another $$48^{\circ}$$ (indicated by $$\angle 1$$). There is also an angle labeled $$32^{\circ}$$. Without a clear diagram corresponding to the problem statement, it's impossible to solve. Assuming there is a missing or incorrect diagram, I cannot provide a numerical answer.
