Question

matemática me ajudaaaaa

Determine sebo, cosseno e tangente dos dois ângulos agudos dos triângulos retângulos abaixo.

Answer 1

Boa noite Sthephany

1)

b = 3
c = 4
h = 5

sen(B) = 3/5
cos(B) = 4/5
tg(B) = 3/4 

sen(C) = 4/5
cos(C) = 3/5
tg(C) = 4/3 

2)

b = 5
c = 12
h = 13

sen(B) = 5/13
cos(B) = 12/13
tg(B) = 5/12

sen(C) = 12/13
cos(C) = 5/13
tg(C) = 12/5


3)

b = 9
c = 12
h = 15

sen(B) = 9/15 = 3/5
cos(B) = 12/15 = 4/5
tg(B) = 3/4 

sen(C) = 12/15 = 4/5
cos(C) = 9/15 = 3/5
tg(C) = 4/3 

4)

b = 6
c = 8
h = 10

sen(B) = 6/10 = 3/5
cos(B) = 8/10 = 4/5
tg(B) = 3/4 

sen(C) = 8/10 = 4/5
cos(C) = 6/10 = 3/5
tg(C) = 4/3
