Hi there,
\n" ); document.write( "Consider the mast and wires as a right
\n" ); document.write( "angled triangle.
\n" ); document.write( "The wire is the hypotenuse
\n" ); document.write( "The mast is the opposite side
\n" ); document.write( "The mast size^2 + ground length^2
\n" ); document.write( "= wire length^2
\n" ); document.write( "So, 40^2 + 20^2 = wire length^2
\n" ); document.write( "1600 + 400 = wire length^2
\n" ); document.write( "wire length^2 = 2000
\n" ); document.write( "wire length = √2000
\n" ); document.write( "wire length = 44.721
\n" ); document.write( "3 wires = 3 x 44.721
\n" ); document.write( "3 wires = 134.2ft
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
