Question

nos triângulos a seguir, determine os valores de sen a, cos a , Tg a, sen b , cos b, tg b. AJUDAAAAAAA
$\sin( \alpha \cos( \alpha \tan( \alpha \sin( \beta \cos( \beta \tan( \beta ) ) ) ) ) )$

Answer 1

sen x = cateto oposto / hipotenusa

cos x = cateto adjacente / hipotenusa

tg x = sen x / cos x

(A)

sen α = 12/13

cos α = 5/13

tg α = sen α / cos α = 12/5

sen β = 5/13

cos β = 12/13

tg β = sen β / cos β = 5/12

(B)

sen α = 8/17

cos α = 15/17

tg α = 8/15

sen β = 15/17

cos β = 8/17

tg β = 15/8
