Question

Se considera doua unghiuri, AOB si BOC, de 45 grade, respectiv de 30 grade si se noteaza m(AOC) =x. Cele doua unghiuri sunt adiacente numai daca: A. x=15 grade B.15 grade<x<75 grade     C. x=75 grade    D.x>75 grade

Answer 1

Cele doua sunt adiacente daca si numai daca
m(<AOB)+m(<BOC)=45+30=75 de grade ⇔
m(<AOC)=75 de grade⇒varianta c.
