Question

Determine o valor de x+y me explica a conta por favor

Answer 1

primer triangulo

tg B = ac/ab
tg 30 = x/300
X=300 x tg30
X=300(\/3/3)
x= 100\/3

segundo triangulo

tgB' = ac/ab
tg60 = 100\/3/y
tg60 . y = 100\/3
\/3y=100\/3
y=100\/3/\/3
y=100

valor de x+y

£=x+y
£=100\/3 + 100
£=200\/3

a resposta e 200\/3
