    I found the complete question and its corresponding choices.

    Given:

    Based on the figures the angles are 15° and 20°

    The opposite is 2 feet.

    We are looking for the value of the adjacent.

    Using the tan function.

    tan θ = opposite / adjacent

    adjacent = opposite / tan θ

    adjacent = 2 / tan (15°) = 7.46 feet

    adjacent = 2 / tan (20°) = 5.49 feet

    7.49 feet - 5.49 feet = 1.97 feet

    If Owen will use the 15° angle, the ramp needs to be 7.46 feet long.

    If Owen will use the 20° angle, the ramp needs to be 5.49 feet long.
