Question

In diagrama circulara alaturata , daca raportul x/y = 7/17 , aflati x si y .

Answer 1

$\frac{x}{y} = \frac{7}{17} \\ x + y = 360 - 120 \\ x + y = 240 \\ \frac{x}{7} = \frac{y}{17} = k \\ x = 7k \\ y = 17k \\ 7k + 17k = 240 \\ 24k = 240 \\ k = 240 \div 24 \\ k = 10 \\ x = 7 \times 10 = 70 \\ y = 17 \times 10 = 170$
