    Answer: Casey is standing 52.5 feet from the lighthouse.

    Step-by-step explanation:

    A right angle triangle is formed. The height of the lighthouse represents the opposite side of the right angle triangle. The distance, h from the lighthouse to where Casey is standing represents the adjacent side of the right angle triangle. Casey's line of sight along the angle of elevation represents the hypotenuse.

    To determine h, we would apply

    the tangent trigonometric ratio.

    Tan θ, = opposite side/adjacent side. Therefore,

    Tan 58 = 84/h

    h = 84/tan 58 = 84/1.6

    h = 52.5 feet

    Answer: 52.489 ...

    Step-by-step explanation:

    Angle of elevation is 58 degrees, and the opposite value is 84 feet, so you're lookin g for adjacent. That means you'll use tangent to solve this equation:

    Tan (58) = 84/x
