    The correct answer is - option b. 90.6

    Explanation:

    The scalar x-component of a vector can be expressed as the product of its magnitude with the cosine of its direction angle

    If you shine a light straight down onto that vector, then the length of its shadow on the x-axis is -

    x-component = 112· cosine (36°)

    x-component = 112 · (0.8090)

    x-component = 90.60

    Thus, The correct answer is - option b. 90.6
