Question

aflati.masurile unui patrulater convex stiind ca sunt invers proportionale cu0,5;0,(3);0,25;0,1(6)

Answer 1

banuiesc ca unghiurile unui patrulater?!
suma unghiurilor=360 grade

A+B+C+D=360
unghiurile sunt invers proportionale cu 0,5; 0,(3),; 0,25;0,1(6)

A/1/0,5=B/1/0,(3)=C/1/0,25=D/1/0,1(6)=k
A/1/5/10=B/1/3/9=C/1/25/100=D/1/15/90=k
Ax10/5=Bx9/3=Cx100/25=Dx90/15=k
2A=3B=4C=5D=k
2A=k  =>A=2k
3B=k  =>B=3k
4C=k  =>C=4k
6D=k  =>D=6k

A+B+C+D=2k+3k+4k+6k=360 grade
15k=360
k=360:15
k=24
egalam fiecare unghi cu k
A=2k  =>A=48grade
B=3k  =>B=72 grade
C=4k  =>C=96 grade
D=6k  =>D=144grade
