Question

Să se afle cinci unghiuri in jurul unui unghi care au masurile invers proportionale cu 2,3,4,6,12.
vă rog frumos!♡

Answer 1

Fie unghiurile A,B,C,D,E

m=raport de proportionalitate

A=m/2
B=m/3
C=m/4
D=m/6
E=m/12

A+B+C+D+E=360
m/2+m/3+m/4+m/6+m/12=360
cmmmc(2,3,4,6,12)=12
m/2+m/3+m/4+m/6+m/12=360 l x12
6m+4m+3m+2m+m=360x12
16m=360x12
m=(360x12)/16

m=270

A=135
B=90
C=67grd si 30'
D=45
E=22grd si 30'
