cossec130°
cossec15°
cossec67°
cossec215°
cossec80°

Answer 1

Resposta:Segue as contas abaixo na explicação

Explicação passo-a-passo:

a)Cossec 125°=1/sen 125

  Cossec 125°=1/0,82

  Cossec 125°=1,22

b)Cossec 130°=1/sen 130

  Cossec 130°=1/0,766

  Cossec 130°=1,305

c)Cossec 15°=1/sen 15

  Cossec 15°=1/0,25882

  Cossec 15°=3,86

d)Cossec 67°=1/sen 67

  Cossec 67°=1/0,92

  Cossec 67°=1,087

e)Cossec 215°=1/sen 215

  Cossec 215°=1/-0,57

  Cossec 215°=-1/75

f)Cossec 80°=1/sen 80

  Cossec 80°=1/0,985

  Cossec 80°=1,015
