Question

Determinati masurile unui patrulater convex stiind ca acestea sunt direct proportionale cu 3,5,4 si 6 .

Answer 1

ABCD=360
m(<A)=3k
m(<B)=5k
m(<C)=4k
m(<D)=6k
m(<A)+m(<B)+m(<C)+m(<D)=360⇔
3k+5k+4k+6k=360
18k=360⇒
k=360:18
k=20

m(<A)=3x20⇒60
m(<B)=5x20⇒100
m(<C)=4x20⇒80
m(<D)=6x20⇒120          Proba: 60+100+80+120=360
