Question

Determine os valores de sen α, cos α, tg α, sen β, cos β e tg β.

Answer 1

Olá!

Seja a=25cm; b=24cm e c=7cm.

sen α= c/a
sen α=7/25
sen α=0,28

cos α=b/a
cos α=24/25
cos α=0,96

tg α=c/b
tg α=7/24
tg α=0,29

sen β=b/a
sen β=24/25
sen β=0,96

cos β=c/a
cos β=7/25
cos β=0,28

tg β=b/c
tg β=24/7
tg β=3,43
