Question

Determinati masurile unghiurilor unui patrulater convex,stiind ca aceste sunt direct proportionale cu 3,4,5 si respectiv 6

Answer 1

+b+c+d=360grade
a/3=b/4 =c/5 =d/6
a+b+c+d/ 3+4+5+6 =360 /18 =20
a/3 =20  ; a=3*20 =60 gr.
b/4 =20  ;b=4*20 =80 gr
c /5 =20  ; c=5*20 =100 gr
d /6 =20  ; d =6*20 =120 gr
( V:  60+80+100+120 =360 grade  )
