4. Suppose sin(A) = 0.422, where A is an angle in a triangle. (12 points)a. One possibility for angle A is A = sin-(0.422) z 25°. What is another possible

value for A?Explain why there are two possible values. b. Suppose you were told that there is another angle, B, in the triangle, and B = 35°. Are both of your angles from part a still valid? Please explain your answer.
