    Answer:

    70.5°

    Step-by-step explanation:

    To solve for the ladder’s angle of elevation, we solve using the Trigonometric function of Cosine

    = cos θ = Adjacent/Hypotenuse

    Where

    Adjacent = Distance of the base from the house = 10ft

    Hypotenuse = Length of the ladder = 30 ft

    cos θ = 10/30

    cos θ = 1/3

    θ = arc cos 1/3

    θ = 70.528779366

    Approximately = 70.5°

    Therefore, the ladder’s angle of elevation is 70.5°
