one cable attached 5 feet away from the pole on the ground and connected to the top of the pole would be equal to 13 feet in length.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is because the cable is the hypotenuse of a right triangle that has a height of 12 feet and a base of 5 feet.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a^2 + b^2 = c^2 in a right triangle.
\n" ); document.write( "a = 5
\n" ); document.write( "b = 12
\n" ); document.write( "formula becomes:
\n" ); document.write( "5^2 + 12^2 = c^2 which becomes:
\n" ); document.write( "c^2= 169 which becomes:
\n" ); document.write( "c = 13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so each cable is 13 feet in length.
\n" ); document.write( "there are 3 cables per pole and 4 poles.
\n" ); document.write( "total length of cable is 3 * 4 * 13 = 156 feet.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
