Answer 1

Respuesta:

1) 18.79 km

2) 1.8 m

Explicación paso a paso:

1)

${x}^{2} = {8}^{2} + {17}^{2} \\ {x}^{2} = 64 + 289 \\ {x}^{2} = 353 \\ x = \sqrt{353} \\ x = 18.79$

2)

${3}^{2} = {2.8}^{2} + {x}^{2} \\ 9 = 7.84 + {x}^{2} \\ 9 - 7.84 = {x}^{2} \\ 1.16 = {x}^{2} \\ \sqrt{1.16} = x \\ 1.08 = x$
