Answer:
A. Cos S
Step-by-step explanation:
Recall: SOH CAH TOA
Sin W = Opp/Hyp
Opposite = 4
Hypotenuse = 5
Sin W = 4/5
Let's find the ratio for each option given to determine which gives us the same ratio as Sin W.
Option A: Cos S
Cos S = Adj/Hyp = 4/5
Option B: tan W
Tan W = Opp/Adj = 4/3
Option C: cos W
Cos W = Adj/Hyp = 3/5
Option D: sin S
Sin S = Opp/Hyp = 3/5
✔️Thus, sin W = cos S = 4/5
The correct option is A
