Question

Utilizando os dados aproximados da tabela 2,
calcule o que se pede.

Answer 1

Resolvendo:

I. Valor de AC = x.

$sen \:\beta =\frac{x}{100} \\\\\frac{x}{100}=0,84\\\\x=84$

II. Valor de AB = x.

$cos \:\beta =\frac{x}{200} \\\\\frac{x}{200} =0,17\\\\x=34$

III. Valor de BD = x + y.

$tg\:\alpha =\frac{y}{300} \\\\\frac{y}{300} =0,84\\\\y=252\\\\\\tg\:\beta =\frac{x}{300} \\\\\frac{x}{300} =0,37\\\\x=111\\\\\\x+y=111+252=363$

Espero ter ajudado!

Desculpe qualquer erro.
