Answer:
The diagram accompanying the question is missing, I found a possible matching diagram, and it is attached to this answer.
The correct answer is:
Cos(C)
Step-by-step explanation:
First of all not the following:
Sin(θ) = [tex]\frac{opposite}{hypotenous}[/tex]
Cos(θ) = [tex]\frac{Adjacent}{hypotenous}[/tex]
Tan(θ) = [tex]\frac{opposite}{adjacent}[/tex]
From the diagram:
Sin(A) = [tex]\frac{BC}{AC}[/tex]
similarly,
Cos(C) = [tex]\frac{BC}{AC}[/tex]
Therefore, Sin(A) = Cos(C)
