Question

Care este masura unghiurilor unui patrulater convex , direct proportionale cu 2,5,7,10??

Answer 1

{A,B,C,D}dp{2,5,7,10}
A/2=B/5=C/7=D/10=K
A+B+C+D=360 GRADE
A/2=K⇒  A=2K
B/5=K⇒ B=5K
C/7=K⇒ C=7K
D/10=K⇒ D=10K
2K+5K+7K+10K=360
24K=360
K=360/24
K=15
A=2K=2·15=30 GRADE
B=5K=5·15=75 GRADE
C=7K=7·15=105 GRADE
D=10K=10·15=150 GRADE
30+75+125+150=360 GRADE
