If the two triangle ends (both as right-triangles) could be shuved together to get rid of the rectangular part, then there are \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Left right triangle: leg x and y, angle opposite of y is 34 degree; angle opposite of x is 56 degree.
\n" ); document.write( "Right right triangle: leg 100-x and y, angle opposite of y is 48 degree, and angle opposite of 100-x is 42 degree.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The two triangles together form a segment of 220-120=100 meters; split into x and 100-x.\r
