WebThe three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent. WebSOLUTION. Step 1: Use ∠C as the reference angle to determine the adjacent and opposite side. Hence, C A ¯ is adjacent to ∠C, A T ¯ is opposite to ∠C, and B C ¯ is the hypotenuse. Step 2: Given A C ¯ and ∠C=32°, use the derived formula for the missing length of the hypotenuse. Thus, h = a cos θ.
