The sizes of the vertex angles of isosceles triangles ABC, ACD, ADE, AEF and AFG at the common Vertex A are respectively 24°, 26°, 28°, 30° and 32. Let M be the intersection of paragraphs FA and GD, K be the intersection of paragraphs FB and GD, and n be the intersection of paragraphs FB and EA. Find the sizes of the angles AMK, MKN and KNA.
