Todos em Fração

Answer 1

Cos330=0.866025403
O.86=43/50

Cos60=1/2
Cos180=-1
Cos120=-1/2
Cos240=-1/2
Cos135=-7/10
Cos270=0
Cos45=7/10
Cos210=-43/50
Cos315=7/10
Cos150=-43/50
Cos90=0
Cos30=43/50
Cos300=1/2
Cos360=1
Cos0=1
Cos225=-7/10

Answer 2

cos330°= 0.86

cos60°= 0.5

cos180°= -1

cos120°= -0.5

cos240°= -0.5

cos135°= -0.70

cos270°= 0

cos45°= 0.70

cos210°= -0.86

cos315°= 0.70

cos150°= -0.86

cos90°= 0

cos30°= 0.86

cos300°= 0.5

cos360°= 1

cos0°= 1

cos225°= -0.70

Espero ter ajudado!

Boa sorte!!
