You can put this solution on YOUR website!
tan(42) = 1.8/x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 1.8/tan(42)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 1.999... \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is reasonable since, if the angle was 45 degrees, the shadow would have been 1.8 meters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1.8 is the opposite side of the angle.
\n" ); document.write( "x is the adjacent side of the angle.
\n" ); document.write( "the hypotenuse of the right triangle formed is the direct line from the end of the shadow to the sun.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that line and the ground form the angle of elevation.\r
