jika tgx = 4/3 maka cosecx= ... a.3/4 b.4/3 c. 4/5 d. 5/4 e, 5/3 jelaskan jawabanya dong Gan

tg x = 4/3 = depan/samping
»»
Sisi depan = 4
Sisi samping = 3
Sisi miring = akar(4² + 3²) = 5

cosec x = miring/depan = 5/4

Jawaban : D

Mapel : Matematika
Kelas : X SMA
Bab : Trigonometri

Pembahasan :
Tan x = Depan/Samping
Tan x = 4/3

Depan = 4
Samping = 3
Miring = 5 (Triple Pythagoras)

Maka...
Sin x = Depan/Miring
Sin x = 4/5
1/Sin x = 5/4
Cosec x = 5/4

Jawaban : D
