Question

Aflati masurile unghiurilor unui patrulater convex , daca ele sunt direct proportionale cu numere 6,8,10,12

Answer 1

a+b+c+d =360 grade

a/6+b/8+c/10+d/12 =a+b+c+d/ 6+8+10+12=360/36 =10

a/6 =10 ;      a =6*10 =60 grade

b/8 =10 ;      b =8*10 =80 gr.

c/10 =10 ;       c=10*10 =100 gr.

d/12 =10 ;        d =12*10 =120 gr
