\n" ); document.write( "Answer: The three sides are 21 m, 21 m, 31 m\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "=======================================================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Explanation:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = length of each of the two congruent sides
\n" ); document.write( "x+10 = length of the third longer side\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The three sides add up to the perimeter 73 meters
\n" ); document.write( "side1+side2+side3 = perimeter
\n" ); document.write( "(x)+(x)+(x+10) = 73
\n" ); document.write( "3x+10 = 73
\n" ); document.write( "3x = 73-10
\n" ); document.write( "3x = 63
\n" ); document.write( "x = 63/3
\n" ); document.write( "x = 21 meters is the length of the two congruent sides
\n" ); document.write( "x+10 = 21+10 = 31 meters is the longer side\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "21+21+31 = 73
\n" ); document.write( "The answers are confirmed.
