a)Daca BC=12 cm si m(C)=30 grade atunci AB=......cm
b)Daca AB=10 cm si m(C)=30 grade atunci BC=......cm
c)Daca AB=8 cm si m(B)=60 grade atunci BC=...cm
d)Daca BC=24 cm si m(B)=60 grade atunci AB=....cm

Answer 1

a)Daca BC=12 cm si m(C)=30 grade atunci AB=6 cm
b)Daca AB=10 cm si m(C)=30 grade atunci BC=20 cm
c)Daca AB=8 cm si m(B)=60 grade atunci BC=16cm
d)Daca BC=24 cm si m(B)=60 grade atunci AB=12cm
