Answer:


{ \tt{ (3x + 6)\degree + 41\degree + (6x - 5)\degree + (4x + 7)\degree + 62\degree + (7x - 11)\degree = 360\degree}} \\ { \tt\{external \: angle \: sum \}}

» Solve:


{ \tt{(3x + 6x + 4x + 7x) + (41 + 6 - 5 + 7 + 62 - 11) = 360}} \\ { \tt{20x + 100 = 360}} \\ { \tt{20x = 260}} \\ { \tt{x = 13}}

x is 13
