The sum of the lengths of any two sides of a triangle must be greater than the third side. If a triangle has one side that is 21 cm and a second side that is 3 cm less than twice the third side, what are the possible lengths for the second and third sides?
\n" ); document.write( "1st side:: 21 cm
\n" ); document.write( "2nd side: 2x-3 cm
\n" ); document.write( "3rd side: x
\n" ); document.write( "------\r
\n" ); document.write( "\n" ); document.write( "Equations because sum of 2 sides must be greater that remaining side:
\n" ); document.write( "2x-3+21 > x
\n" ); document.write( "3x-3+x > 21
\n" ); document.write( "x+21 > 2x-3
\n" ); document.write( "---------------------

\n" ); document.write( "x+18 > 0
\n" ); document.write( "4x > 24
\n" ); document.write( "x < 24
\n" ); document.write( "----
\n" ); document.write( "3rd side:: 6 < x < 24
\n" ); document.write( "2nd side:: 9< 2x-3 < 45
