    =64 ft

    Step-by-step explanation:

    The wire, the pole and the flat surface form a right triangle with a base angle of 40°. The pole is the height of the triangle and is opposite the angle 40°.

    Therefore we can use the trigonometric ratio - sine of the angle 40° - to find the height.

    Sin∅ = opposite/hypotenuse

    opposite=hypotenuse * sin∅

    =100ft * Sin 40°

    =64.28ft

    ≅64 ft
