Question

3) Determine o valor de y:

4) Determine a medida do seguimento AC:

Answer 1

Resposta:

3)

$tg 60=\frac{y}{\sqrt{3} } \\\\\sqrt{3} =\frac{y}{\sqrt{3} } \\\\y=\sqrt{3} . \sqrt{3} \\y=\sqrt{9} \\y=3$

4)$tg30=\frac{x}{9} \\\\\frac{\sqrt{3} }{3} =\frac{x}{9} \\\\3x=9\sqrt{3}$

$x= \frac{9\sqrt{3} }{3}\\x=3\sqrt{3}$

y=3

x=3√3

x é o segmento AC
