A,B,C,D invers proporțional cu 0,5; 0,(3); 0,25; 0,1(6) . A,B,C,D sunt unghiuri in patrulater convex adica in total 360 grade

Answer 1

a+b+c+d=360
0,5=5/10=1/2
0,(3)=3/9=1/3
0,25=25/100=1/4
0,1(6)=(16-1)/90=15/90=3/18=1/6
a/2=b/3=c/4=d/6=k
a=2k
b=3k
c=4k
d=6k
2k+3k+4k+6k=360
15k=360 =>k=24
=>a=48
=>b=72
=>c=96
=>d=144
