There are two poles of equal height 15mts. One cable with length 16mts is hanging between that two poles. The height from center of the cable to earth is 7mts then what is the distance between that two poles?

• The distance between poles is zero. In this case, the cable will be hanging directly down and its center be 8mts down which is half of its length. The height of the poles are 15mts, so 15mts - 8mts = 7mts.
