Question

Determine a medida de x na figura

Answer 1

Resposta:

20$\sqrt{6}$

Explicação passo-a-passo:

tg 60= $\frac{ab}{20}$

$\sqrt{3}$= $\frac{ab}{20}$

ab= 20$\sqrt{3}$

sen 45= $\frac{ab}{x}$

$\frac{\sqrt[2]{2} }{2}$ =$\frac{20\sqrt[2]{3} }{x}$

x= $20\sqrt{3}$ *$\frac{2}{\sqrt[2]{2} }$

x= $\frac{40\sqrt{3} }{\sqrt{2} }$ * $\frac{\sqrt{2} }{\sqrt{2} }$

x= $\frac{40\sqrt{6} }{2}$

x= 20$\sqrt{6}$
