\n" ); document.write( "\n" ); document.write( "Should be lower right triangle vertical leg 72 feet, the two nonright angles 46 and 44 degrees.
\n" ); document.write( "Upper right-triangle the nonright angles 31 degrees and 59 degrees.
\n" ); document.write( "The two triangles share a horizontal leg.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If x is the length of the shared horizontal leg, then\r
