Step-by-step explanation:

α0=111  α0 > 90° α0 > 180° 111°=1
α1=113  α1 > 90° α1 > 180° 113°=1
α2=47  α2 < 90° α2 < 180° 47°=0
α3=85  α3 < 90° α3 < 180° 85°=0
α4=13  α4 < 90° α4 < 180° 13°=0
α5=157  α5 > 90° α5 > 180° 157°=1
α6=172  α6 > 90° α6 > 180° 172°=1
α7=117  α7 > 90° α7 > 180° 117°=1
α8=54  α8 < 90° α8 < 180° 54°=0
α9=186  α9 > 90° α9 > 180° 186°=0
