Question

abcd patrulater conv a b direct prop cu 3 si 5 si b c d invers prop cu 0,1 0,2 0,0 perioada 6

Answer 1

a/3=b/5=k
a=3k
b=5k

0,1=1/10
0,2=2/10=1/5
0,0(6)=6/90=1/15
b/10=c/5=d/15=k'
b=10k' ; b=5k =>k=2k'
c=5k'=10k
d=15k'=30k

3k+5k+10k+30k=360°
48k=360° =>k=7,5
a=22°30'
b=37°30'
c=75°
d=225°
