    Question

    What ratio would you use to solve for x?

    1. Sine ratio
    2. Cosine ratio
    3. Tangent ratio
    4. Cot ratio

    Hint:

    cos x = adjacent side/hypotenuse side

    The correct answer is: Cosine ratio

      Cosine ratio should be used to solve for x.
      Since the adjacent and angle vales are given we need to find hypotenuse side
      cos x = adjacent side/hypotenuse side
