Question

Observe a figura seguinte e determine tg30graus = raiz de 3 sobre 3 tg60 graus = raiz de 3

Answer 1

a)

tg30°=co/ca

$\frac{ \sqrt{3} }{3} = \frac{x}{300}$

$3x=300 \sqrt{3} \\ x= 300 \sqrt{3} \div3 \\ x=100 \sqrt{3}~cm$

b)
tg60°=co/ca

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

$\sqrt{3} = \frac{100 \sqrt{3} }{y}$

$y= \frac{100 \sqrt{3} }{ \sqrt{3} }$

$y=100~cm$

c)

$AD=300-100 \\ AD=200~cm$
