Question

calcule x nos triângulo retângulo acima
Pra amanhã

Answer 1

Olá

a)

sen35° = cat.op / hip

0,57 = x / 20

x = 11,4

b)

cos60° = cat.ad / hip

1 / 2 = x / 40

2x = 40

x = 40 / 2

x = 20

c)

tg50° = cat.op / cat.aj

1,19 = x / 100

x = 119

d)

cos45° = cat.aj / hip

√2 / 2 = x / 10

2x = 10√2

x = 10√2 / 2

x = 5√2

e)

tg60° = cat.op / cat.ad

√3 = x / 30

x = 30√3
