Coh: sin(theta) = Opp/Hyp
sin(theta°) = AC/AB
sin(70°) = AC/4
AC = 4*sin(70°)
AC ≈ 3.758770483
AC = 3.76
In order: 32°, 78°, 71°, 54° , 154°, 113° , 81° , 77° , 91° , 83° , 159° , 86° hope this helps just color in order of the degrees given and it will lead you to the end.
The answer would be b, hope it helps!
