In triangle abc, you know that a = 2, b = 3 and m < a = 30°. which option below lists the number of triangles and gives the correct explanation?

there are no triangles because b sin a < a.
there is exactly one triangle because b sin a = 0.5b.
there are two triangles because b sin a < a < b.
there are three triangles because b sin a = 0.5b and b sin a < a < b.
