Ineed quickly with these problems see the images you so much

By law of the sine we have:
 sine (x) / 38 = sine (35) / 22
 Clearing we have:
 sine (x) = (sine (35) / 22) * (38)
 x = asine ((sine (35) / 22) * (38))
 x = 82.18949277
 Rounding:
 x = 82.2 degrees
 
 The answer for this case is given by:
 x = 82.2 degrees
