Answer 1

Resposta:

$d=100\sqrt{6}m$

Explicação passo-a-passo:

$\frac{a}{sen a} =\frac{b}{sen b}$

$\frac{300}{sen 60} =\frac{d}{sen 45}$

$\frac{300}{\frac{\sqrt{3}}{2} } =\frac{d}{\frac{\sqrt{2}}{2}}$

$300*\frac{\sqrt{2}}{2} =d*{\frac{\sqrt{3}}{2}$

$150\sqrt{2} ={\frac{d\sqrt{3}}{2}$

$150\sqrt{2}*2 =d\sqrt{3}$

$300\sqrt{2} =d\sqrt{3}$

$d=\frac{300\sqrt{2}}{\sqrt{3}}$

$d=\frac{300\sqrt{2}}{\sqrt{3}} *\frac{\sqrt{3}}{\sqrt{3}}$

$d=\frac{300\sqrt{6}}{3}$

$d=100\sqrt{6}m$
