Solution Steps

Step 1: Identify the correct trigonometric ratio for Cosine

The cosine of an angle in a right triangle is defined as the ratio of the length of the adjacent side to the hypotenuse. Mathematically, this is represented as: \[ \cos(\theta) = \frac{\text{Adjacent}}{\text{Hypotenuse}} \]

Step 2: Compare with the given options

The given options are:

  1. Opp/Hyp
  2. Adj/Opp
  3. D

From the definition of cosine, the correct ratio is Adjacent/Hypotenuse, which corresponds to the second option: Adj/Opp.

Step 3: Conclude the correct answer

The correct ratio for cosine is Adj/Opp.

Final Answer

The correct answer is B.
