Question

No .4,5,6 tentukan nilai 6 perbandingan trigonometri (sin,cos,tan,sec,cosec,cotan) beserta caranya.

No 7. Tentukan nilai x,y,r dari segitiga dibawah ini beserta caranya


Nb: tolong banget ya bantuannya

Answer 1

Sin = Depan/Miring
Cos = Samping/Miring
Tan = Depan/Samping
Cosec = Miring/Depan
Sec = Miring/Samping
Cot = Samping/Depan

4) Sin alpha = a/c
Cos alpha = b/c
Tan alpha = a/b
Cosec alpha = c/a
Sec alpha = c/b
Cot alpha = b/a

5) sin beta = x/z
Cos beta = y/z
Tan beta = x/y
Cosec beta = z/x
Sec beta = z/y
Cot beta = y/x

6) Sin R = q/r
Cos R = p/r
Tan R = q/p
Cosec R = r/q
Sec R = r/p
Cot R = p/q

7) Gada gambarnya...
