It requires about 283.9 ft of wire.

Explanation:

We have a right triangle with a #65^circ# angle. The side adjacent to the angle, along the ground (or horizontal) is 120 ft long. We're looking for the hypotenuse of the triangle.

Since we know an angle, the side adjacent to the angle, and want the hypotenuse, we use cosine.

#cos(65^circ) = 120/h \rightarrow h =120/cos(65^circ) approx 283.944# ft.
