Question

determinati masurile a doua unghiuri suplimentare al caror raport este 3/2

Answer 1

Notez masurile unghiurilor cu x si y.

x+y=180 (grade)

$\frac{x}{y} = \frac{3}{2}$ => x=$\frac{3y}{2}$

x+y=180 <=> $\frac{3y}{2} + y=180 <=> \frac{3y}{2} + \frac{2y}{2} =180$ <=> $\frac{5y}{2} = 180 => y= \frac{2*180}{5} = 72$ (grade) => y=108 grade.

Masurile unghiurilor sunt 108 grade si 72 grade.
