Sisi samping = 12 Sisi miring = 13 Tentukan nilai dari: a. Sin b. Cos c. Tan

Materi : Trigonometri
Kelas : X SMA

Sisi Samping = 12
Sisi Miring = 13
Sisi Tegak = .....?

Use Theorema Phitagoras Form :

If :
A = sisi Samping
B = Sisi Tegak / Depan
C = Sisi Miring

C^2 = A^2 + B^2
13^2 = 12^2 + B^2
169 = 144 + B^2
B^2 = 169 - 144
B^2 = 25
B = 5

Sin = Depan / Miring
Sin= 5/13

Cos = Samping / Miring
Cos = 12/13

Tan = Depan / samping
Tan = 5/12
