Previous Question Suppose that in solving an equation over the interval (0,360), you reach the step sin 0 - - Why -30° not a correct answer? 2 Choose the correct answer below. O A. Because - 30° is not in the range of the inverse sine function. 1 OB. Because sin - - when 0 - - 150 c. Because the solution should be in the interval [0,360°),
