Question

DADO O TRIÂNGULO RETÂNGULO ABC.DETERMINE:                                      

                                                               B                             Sen B             sen c

                                                               |\                              Con B              cos c

                                                               |   \   12                   Tg B                 Tg  c

                                                        20  |     \           

                                                               |. ___\   c                                   

                                                               A   16                                 

 

 

Tem um ponto dentro do triangulo perto da letra A.       

Não sei fazer triangulo então foi o unico jeito.

                                                            

deu pra entender ?

Answer 1

$sen(B)= \frac{cat~oposto}{hipotenusa}~\to~sen(B)= \frac{16}{12}~\to~sen(B)= \frac{4}{3}$

$cos(B)= \frac{cateto~adjacente}{hipotenusa}~\to~cos(B)= \frac{20}{12}= \frac{5}{3}$

$tan(B)= \frac{cateto~oposto}{cateto~adjacente}~\to~tan(B)= \frac{16}{20}= \frac{4}{5}$
_________________________________________

$sen(C)= \frac{c.o.}{hip}~\to~sen(C)= \frac{20}{12}= \frac{5}{3}$

$cos(C)= \frac{c.a.}{hip}~\to~cos(C)= \frac{16}{12}= \frac{4}{3}$

$tan(C)= \frac{c.o.}{c.a}= \frac{20}{16}= \frac{5}{4}$


Espero ter ajudado e bons estudos :)
