Question

Intr-un triunghi , masurile celor trei unghiuri ale sale sunt direct proportionale cu numerele 2,3 si 4 . Aflati masurile celor trei unghiuri

Answer 1

x/2=y/3=z/4=k
x=2k⇒40°
y=3k⇒60°
z=4k⇒80°
x+y+z=180°
2k+3k+4k=180
9k=180°
k=20°

Answer 2

a+b+c=180
a/2=b/3=c/4=k
a=2k, b=3k, c=4k

2k+3k+4k=180
9k=180
k=20
a=40
b=60
c=80
