Question

ma puteți ajuata la acest exercitiu va rog frumos​

Answer 1

Explicație pas cu pas:

A=6/11 B=16/19C

B=11/6 A

C=19/6 A

A+B+C=180°

A+11/6 A +19/6 A =180°

A (1+11/6+19/6)=180°

A×6+11+19/6=180°

36/6 A =180°

6A=180°

A=180°/6

A=30°

B=11/6 A =11/6×30=11×5=55°

B=55°

C=19/16 A=19/16×30=19×5=95°

C=95°

Verificare :

A+B+C=30°+55°+95°180°
