Question

Determina masura unghiului VOM unde {O}=GM intersesctat EF​

Answer 1

Răspuns:

tr. EGM echilateral, EM=6 cm

P trEGM =3x l=3x6=18 cm

tr. VGE=isoscel, GE congruent cu GV=6 cm

m(EGV) =90 grade +60 grade =150 grade

m(GVE) =m(GEV) =180 grade - 150 grade/2=15 grade

m(VOM) =180 grade - (m (OMV) +m(OVM))

=180 grade - (45 grade+30 grade)

=180 grade-75 grade

=105 grade
