Ce masura are complementul unui unghi al carui suplement are masura de 140 grade ?

Răspuns :

Unghi + Suplement = 180 grade
Unghi + 140 grade = 180 grade
Unghi = 180-140 grade
Unghi = 40 grade
Complement = 90 grade - 40 grade
Complement = 50 grade

Economist
1) masura unghi + suplement = 180 grade
    masura unghi + 140 grade = 180 grade
    masura unghi = 180 grade - 140 grade
    masura unghi = 40 grade
2) masura unghi + complement = 90 grade
   40 grafe + complement = 90 grade
   complement = 90 grade - 40 grade
   complement = 50 grade
