Esercizio:
b=348,75m
[a]=90°03'24" = 90°,0567
[b]=49°13'47" = 49°,2297
[c]=180-(90,0567+49,2297) = 40,7136
a=b x sen[a]/sen[b] = 348,75 x sen90,0567/sen49,2297 = 460,497m
c=b x sen[c]/sen[b] = 348,75 x sen40,7136/sen49,2297 = 300,372m
s=0,5ab x sen[c] = 0,5 x 460,497 x 348,75 x sen40,7136 = 52377,41m2
