Use the law of sines to find the missing angle in the triangle. find m

Using the law of the sines we have:
 (13) / (sin (40)) = (19) / (sin (C))
 Clearing the angle C we have:
 sin (C) = (19/13) * (sin (40))
 C = Asin ((19/13) * (sin (40)))
 C = 69.96086904
 Rounding:
 C = 70 degrees
 
 The missing angle in the triangle using the Law of Sines is:
 70 degrees
