A 100 foot tall antenna sits part way up a hill. The hill makes an angle to 12 degrees with the horizontal. In other words, if you were going to walk up the hill, you would walk at an angle of 12 degrees. To keep the antenna stable, it must be anchored by 2 cables.The distance from the base of the antenna to the down point DOWN hill is 95 feet.Ignore the amount of cable needed to fasten the cable to the antenna or to the tie downs. How much cable is needed?

Please Draw and label if you can or give me the idea of this question.

1. Ok, on the down side cable. 100 distance up, 95 distance downhill, and the angle between those you can figure your self. YOu have SAS. Use the law of cosines to figure the cable length , you are given two sides, and included angle.

On the other cable, you present no info on how it is hooked up.
