A flagpole has a height of 66 yards. It will be supported by three cables, each of which is attached to the flagpole at a point 6 yards below the top of the pole and attached to the ground at a point that is 32 yards from the base of the pole. Find the total number of yards of cable that will be required

Answer:

The value is [tex]Y = 204 \ yards[/tex]

Step-by-step explanation:

From the question we are told that

   The height of the flag pole is  [tex]h = 66 \ yards[/tex]

   The position of the cables on the pole with respect to its top is  [tex]x = 6 \ yards[/tex]

   The position of the cable from the base of the pole is  [tex]w = 32 \ yards[/tex]

    The number of cables is n =  3

Generally the length of one of the cable is obtained using Pythagoras theorem as follows

       [tex]u = \sqrt{ (h - x)^2 + w^2}[/tex]

=>    [tex]u = \sqrt{ (66 - 6)^2 + 32^2}[/tex]

=>    [tex]u = 68 \ yards[/tex]

Generally the total number of yards of cable that will be required is mathematically represented as

       [tex]Y = 3 * u[/tex]

=>     [tex]Y = 3 * 68[/tex]

=>     [tex]Y = 204 \ yards[/tex]
