Question

calcule o valor de x e y nos triângulos abaixo

Answer 1

a)
Sen30 = Cateto Oposto / Hipotenusa
1/2 = 2/X
X = 4

b)
Sen60 = CO / H
√3/2 = X / 100
X = 100√3 / 2
X = 50√3

c)
Tg45 = Cateto Oposto / Cateto Adjacente
1 = X/20
X = 20

d)
Sen60 = CO / H
√3 / 2 = X / 80
X = 80√3 / 2
X = 40√3


e)
Sen30 = CO / H
1/2 = 80 / X
X = 160
