Question

Dau 55 pct .Se da un patrulater convex. Sa se afle masurile unghiurilor stiind ca sunt direct proporionale cu 3 4 5 6

Answer 1

{a, b, c, d} d. p. {3,4,5,6}

=>a/3=b/4=c/5=d/6=k

a/3=k=>a=3k

b/4=k=>b=4k

c/5=k=>c=5k

d/6=k=>d=6k

3k+4k+5k+6k=18k

Un patrulater convex are suma unghiurilor de 360° deci

360:18=20(k)

a=3x20=60

b=4x20=80

c=5x20=100

d=6x20=120
