\n" ); document.write( "First part of drawing a figure:
\n" ); document.write( "Right triangle, height 138, base length x, hypotenuse, r.
\n" ); document.write( "x is how far the ground attachment of the guy wire;
\n" ); document.write( "71 degrees where guy wire is attached to the ground;
\n" ); document.write( "r, the original wire length from top of tower to attachment point on ground at x away from tower base.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"138%2Fr=sin%2871%29\"\r
\n" ); document.write( "\n" ); document.write( "\"r%2F138=1%2Fsin%2871%29\"\r
\n" ); document.write( "\n" ); document.write( "\"r=138%2Fsin%2871%29\"\r
\n" ); document.write( "\n" ); document.write( "-\r
\n" ); document.write( "\n" ); document.write( "\"cos%2871%29=x%2Fr\"\r
\n" ); document.write( "\n" ); document.write( "\"x=r%2Acos%2871%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x=138%28cos%2871%29%2Fsin%2871%29%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next triangle, also right triangle,
\n" ); document.write( "leg vertical of 138,
\n" ); document.write( "horizontal leg of x+8, and you can now evaluate this leg;
\n" ); document.write( "R, the longer hypotenuse than was r;\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Again, you now should have the value of x:
\n" ); document.write( "\"%28x%2B8%29%5E2%2B138%5E2=R%5E2\"
\n" ); document.write( "and with this you should be able to find R.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First question asks for difference between R and r.
\n" ); document.write( "
\n" );
