Question

examine o triângulo retângulo representando abaixo calcule o valor dessas razões:
a)sen beta
b)cos beta
c)tg beta
d)sen teta
e)cos teta
f)tg teta

Answer 1

A) $sen \beta = \frac{cat.oposto}{hipotenusa} = \frac{4}{5}$

B) $cos \beta = \frac{cat.adjacente}{hipotenusa} = \frac{3}{5}$

C) $tg \beta = \frac{cat.oposto}{cat.adjacente} = \frac{4}{3}$

D) $sen.teta = \frac{cat.oposto}{hipotenusa} = \frac{3}{5}$

E) $cos.teta = \frac{cat.adjacente}{hipotenusa} = \frac{4}{5}$

F) $tg.teta = \frac{cat.oposto}{cat.adjacente} = \frac{3}{4}$
