Remember, even though you enter a rounded answer, do NOT use a rounded number in a future calculation! It is wise to use only given information to find any value. TI84 help Using the Law of Sines to solve the all possible triangles if ZA = 109°, Enter values accurate to 4 decimal places. If no answer exists, enter DNE for all answers. 30, b = 19. ZB is ZC is c = Assume ZA is opposite side a, ZB is opposite side b, and ZC is opposite side c.
