Question

calcule sen,cos e tg dos angulos dados

Answer 1

a)
ângulo α
seno = 3/5
cosseno = 4/5
tangente = 3/4

ângulo β
seno = 4/5
cosseno = 3/5
tangente = 4/3

b) 
ângulo α
seno = 5/√50 = (5*√50) / (√50 *√50) = 5√50/50 = √50/10
cosseno =  5/√50 = (5*√50) / (√50 *√50) = 5√50/50 = √50/10
tangente = 5/5 = 1

c)
ângulo α
seno = 9/√192 = (9*√192) / (√192 * √192) = 9*√192/192 = 3√192/64
cosseno = 11/√192 = (11*√192) / (√192*√192) = 11*√192/192
tangente = 9/11

angulo β
seno = 11/√192 = (11*√192) / (√192*√192) = 11*√192/192
cosseno = 9/√192 = (9*√192) / (√192 * √192) = 9*√192/192 = 3√192/64
tangente = 11/9
