B)200√3
C)90√3
D)25
E)100

Answer 1

Resposta:

a) espero ajudar

Explicação passo-a-passo:

$\frac{x}{ \frac{ \sqrt{3} }{2} } = \frac{100}{ \frac{1}{2} } \\ \frac{ \sqrt{3} }{2} \times 100 = x \times \frac{1}{2} \\ \frac{100 \times \sqrt{3} }{2} = \frac{x}{2} \\x = 100 \sqrt{3 }$

Answer 2

Resposta:

$\frac{x}{sen(120)}=\frac{100}{sen(30)}\\ \\ sen(120)=sen(60)=\frac{\sqrt{3}}{2}\\ \\ \frac{x}{\frac{\sqrt{3} }{2} }=\frac{100}{\frac{1}{2} }\\ \\ \frac{2x}{\sqrt{3} }=\frac{2.100}{1}\\\\ x=\frac{2.100.\sqrt{3} }{2}\\ \\ x=100\sqrt{3}$

bons estudos!
