Question

vcs podem me ajudar?​

Answer 1

Resposta:

(B)

Explicação passo a passo:

1) $\line{\text{AB}} = 500 m$          

$\text{BC} = 600m$ ------> $\text{AC} = 500 + 600 = 1100 m$, $\text{AD} = 1100 + 700 = 1800 m$

$\text{CD} = 700m$

$\text{x} = y - \text{HG}$

$\frac{1800}{1980} = \frac{1100}{y} \Leftrightarrow 1800y = 2178000 \Leftrightarrow y = 1210$

$\frac{1100}{1210} = \frac{500}{\text{HG}} \Leftrightarrow 1100 \cdot \text{HG} = 605000 \Leftrightarrow \text{HG} = 550$

$x = 1210 - 550 = 660$

2) $\frac{1800}{1980} = \frac{600}{x} \Leftrightarrow 1800x = 1188000 \Leftrightarrow x = 660$

Answer 2

Resposta:

B) 660 metros.

Explicação passo a passo:

(500 + 600 + 700) / 1980 = 600/x

1800/1980 = 600/x

1800x = 1980 * 600

1800x = 1188000

x = 1188000/1800

x = 660
