Question

determinati masurile unghiurilor unui patrulater convex stiind ca acestea sunt direct proportionale cu nr 3,4,5,6

Answer 1

U1=3x360/(3+4+5+6)=60
U2=4x360/(3+4+5+6)=80
U3=5x360/(3+4+5+6)=100
U4=6x360/(3+4+5+6)=120

Answer 2

A+B+C+D=360°
A/3=B/4=C/5=D/6=K
A=3k
B=4k
C=5k
D=6k
3k+4k+5k+6k=360°
18k=360°
k=20°
A=3k=3×20°=60°
B=4k=4×20°=80°
C=5k=5×20°=100°
D=6k=6×20°=120°
