Question

Masurile a trei unghiuri in jurul unui punct sunt invers proportionale cu 0,25,0,2 si 0,1IN PARANTEZA 6 .Aflati masurile celor 3 unghiuri.

Answer 1

0,25a=0,2b=0,1(6)c  
0,25a=a/4
0,2b=b/5
0,1(6)c=c/6
a/4=b/5=c/6
5a=4b ⇒ b=5a/4
a/4=c/6 ⇒ c=6a/4
a/4+b/5+c/6=360⁰
a+5a/4+6a/4=360⁰
4a+5a+6a=1440⁰
a=1440⁰:15=96⁰
b=96⁰x5/4=120⁰
c=96⁰x6/4=144⁰
