passo a passo plz !!​

Answer 1

$tangente( \alpha ) = \frac{x}{h} \\ \\ tangente(60°) = \frac{60 \: m}{h} \\ \\ \frac{ \sqrt{3} }{1} = \frac{60 \: m}{h} \\ \\ h \sqrt{3} = 60 \: m \\ \\ \frac{h \sqrt{3} }{ \sqrt{3} } = \frac{60 \: m}{ \sqrt{3} } \\ \\ h = \frac{60}{ \sqrt{3} } \: m \\ \\ h = \frac{60 \sqrt{3} }{( \sqrt{3}) {}^{2} } \: m\\ \\ h = \frac{60 \sqrt{3} }{3} \: m \\ \\ h = 20 \sqrt{3} \: m$
