Question

Intr-un triunghi masurile unghiurilor sunt direct proportionale cu numerele 2,3si5. Sa se determine masurile acestor unghiuri.. repede va rof ajutati-ma

Answer 1

{a,b,c} d.p.{2,3,5}
a=2k=>a=2 ori 18=36
b=3k=>b= 3 ori 18=54
c=5k=> c = 5 ori 18=90
a+b+c=180
2k+3k+5k=180
10k=180
k=18

Answer 2

triunghiul ABC

Suma unghiurilor unui triunghi =180 de grade

a+b+c=180 de grade

a=2k

b=3k

c=5k

2k+3k+5k=10k=180 de grade

1k=180:10=18 grade

a=18 grade x 2=36 de grade

b=18 grade x 3=54 de grade

c=18 grade x 5=90 de grade
