27)

\(\left[ \begin{array} { l c } { Radians:  } & { x = \frac { \pi } { 3 } + 2 \pi n , x = \frac { 2 \pi } { 3 } + 2 \pi n } \\ { Degrees:  } & { x = 60 ^ { \circ } + 360 ^ { \circ } n , x = 120 ^ { \circ } + 360 ^ { \circ } n } \end{array} \right]\) 

29)

\(\left[ \begin{array} { c c } { Radians:  } & { u = \frac { \pi } { 6 } + \pi n } \\ { Degrees:  } & { u = 30 ^ { \circ } + 180 ^ { \circ } n } \end{array} \right]\) 

31)

\(x = \frac { \pi } { 3 } + 2 \pi n , x = \frac { 2 \pi } { 3 } + 2 \pi n , x = \frac { 4 \pi } { 3 } + 2 \pi n , x = \frac { 5 \pi } { 3 } + 2 \pi n\)

(Degrees: \( \quad x = 60 ^ { \circ } + 360 ^ { \circ } n , x = 120 ^ { \circ } + 360 ^ { \circ } n , x = 240 ^ { \circ } + 360 ^ { \circ } n , x = 300 ^ { \circ } + 360 ^ { \circ } n )\)
