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)

Explanation:

First of all not the following:

Sin(θ) =
(opposite)/(hypotenous)

Cos(θ) =
(Adjacent)/(hypotenous)

Tan(θ) =
(opposite)/(adjacent)

From the diagram:

Sin(A) =
(BC)/(AC)

similarly,

Cos(C) =
(BC)/(AC)

Therefore, Sin(A) = Cos(C)
