This is the problem.

Find all real numbers that satisfy the equation. 1 X: cos 2 Select the correct choice below and ll in the answer boxes within your choice. 0 A. kit kit The solution set is {x|x = Cl + ? or x =D + ?}, where k is any integer. (Type an exact answer, using 11: as needed. Type any angles in radians between 0 and 21:. Use ascending order.) 0 B- The solution set is {x|x = Cl + 2km: or x = |:|+ 2kn}, where k is any integer. (Type an exact answer, using 11: as needed. Type any angles in radians between 0 and 21:. Use ascending order.) 0 C. The solution set is {x|x = Cl + km: or x = D + kit}, where k is any integer. (Type an exact answer, using 11: as needed. Type any angles in radians between 0 and 21:. Use ascending order.) 0 D. There is no solution
