ajutorfie triunghiul abc un triunghi cu m < A=90 de grade ,AB=6 cm,BC=10 cm si CA=8 cm calculat a)sin B b)sin C c)cosB d)cos C e) tg B f)tg C g)ctg B h)ctg C multumesccccccccccccccc!!!!!!!!!!!!!!:*
sin de b=ac/bc=8/10 simplificat 2=4/5 sinc=ab/bc=6/10= simplificat cu2=3/5 cos b ab/bc=6/10=3/5 cos c ac/bc=8/10=4/5 tg b ac/ab=8/6=4/3 tg c ab/ac=6/8=3/4 ctg b ab/ac=6/8=3/2 ctg c ac/ab=8/6=4/3 (toate au fost simplificate cu 2)
