Question

Calculati masurile unghiurilor unui triunghi stiind ca sun direct proportionale cu numerele 1, 3 si 5

Answer 1

Explicație pas cu pas:

$\dfrac{x}{1} = \dfrac{y}{3} = \dfrac{z}{5} = \dfrac{x + y + z}{1 + 3 + 5} = \dfrac{180}{9} = 20$

$\dfrac{x}{1} = 20 \implies x = 20 \degree$

$\dfrac{y}{3} = 20 \implies y = 60 \degree$

$\dfrac{z}{5} = 20 \implies z = 100 \degree$
