Risolvi i triangoli (cioè calcola i lati, i seni e i coseni mancanti) in base agli elementi assegnati: 

• a=25, b=17, c=12

• b=29, c=6, cos γ=143/145

• a=20, b=13, sin α =12/13

• a=25, sin α=20/29, cos β=3/5

• c=28 , cos α=8/17, cos γ=13/85

• a=20 , c=21, sin β=3/5

• a=25, b=29, Area =360

• a=20, b=13, c=11

• b=17, cos β=3/5 , sin γ=13/85

• a=20 , b=11, cos γ=4/5

• b=29, c=25, sin γ =20/29

• b=17, c=12, Area =90

• a=13, b=21, c=20

• a=25, c=12, cos α =-8/17
