A short-wave radio antenna is supported by two guy wires, 180 ft and 210 ft long. Each wire is attached to the top of the antenna and anchored to the ground, at two anchor points on opposite sides of the antenna. The shorter wire makes an angle of 65° with the ground. How far apart are the anchor points? (Round your answer to the nearest foot.)

=_______ feet

    180 cos 65 ° = 76.1

    180 sin 65 ° = 163.1 = h ( height of flagpole)

    x ² = 210 ² - 163.1 ²

    x = 132.3 ft

    Distance apart = 76.1 + 132.3 ft = 208 ft ( to nearest whole number )

    completely impractical question.the anchors have to be the same distance from the tower or it will fall over... it will also fall over because you only have two guy wires. you have to have three.
