Question

me ajudem por favor !!!

Answer 1

Rua A = 40 + 30 + 20 = 90

Rua B = x + y + z = 180

$\frac{90}{40} = \frac{180}{x}$

90x = 180*40

x = $\frac{7200}{90}$

x = 80

$\frac{90}{30} = \frac{180}{y}$

90y = 180*30

y = $\frac{5400}{90}$

y = 60

$\frac{90}{20} =\frac{180}{z}$

90z = 180*20

z = $\frac{3600}{90}$

z = 40
