Question

Find all values of \alpha in degrees that satisfy the equation. $\sin3\alpha = -0.4$ Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. (Type integers or decimals rounded to the nearest tenth as needed. Type your answers in degrees. Use angle measures greater than or equal to 0 and less than 360.) A. The solution is \{\alpha | \alpha = \boxed{}^\circ + k\boxed{}^\circ \text{ or } \alpha = \boxed{}^\circ + k\boxed{}^\circ\}, where k is any integer. (Type the smaller positive answer first, followed by the larger positive answer in the same format.) B. The solution set is \{\alpha | \alpha = \boxed{}^\circ + k\boxed{}^\circ\}, where k is any integer. C. There is no solution.

(Type integers or decimals rounded to the nearest tenth as needed. Type your answers in degrees. Use angle measures greater than or equal to 0 and less than 360.) A. The solution is {α| α= ^∘+ k^∘ or α= ^∘+ k^∘}, where k is any integer. (Type the smaller positive answer first, followed by the larger positive answer in the same format.) B. The solution set is {α| α= ^∘+ k^∘}, where k is any integer. C. There is no solution.$
