Question

Me ajuda por favor preciso pra amanhã cedo

Answer 1

Em anexo o desenho do triângulo da letra a

a)

a₁ =

$sen 30= \frac{CO}{hip}\\\\sen 30= \frac{h}{2600}\\\\\frac{1}{2} = \frac{h}{2600} \\\\2h=2600\\h=1300m$

a₂ =

$cos 30= \frac{CA}{hip}\\\\cos 30= \frac{d}{2600}\\\\\frac{\sqrt{3}}{2} = \frac{d}{2600} \\\\2d=2600\sqrt{3} \\\\d=1300\sqrt{3} m$

b)

$sen 60= \frac{CO}{hip}\\\\sen 60= \frac{h}{320}\\\\\frac{\sqrt{3}}{2} = \frac{h}{320} \\\\2h=320\sqrt{3} \\\\h=160\sqrt{3} m$
