This is the question.

. . _ x (5 FInd all real numbers that satisfy the equatlon cos E = 7' Use the smallest nonnegative arcs for the solution set. Select the correct choice below, and if necessary, ll in the answer box(es) to complete your choice. The solution set is {x Ix = |:|+ 6kzc}, where k is any integer. (Use integers or fractions for any numbers in the expression. Use ascending order. Type an exact answer, using 1: as needed.) CA. The solution set is {x Ix = |:|+ 2km: or x =|:| + 2k1t}, where k is any integer. (Use integers or fractions for any numbers in the expression. Use ascending order. Type an exact answer, using 1: as needed.) OB. The solution set is {x Ix = |:|+ 6k): or x =|:| + Skill}, where k is any integer. ' (Use integers or fractions for any numbers in the expression.
