Hi,
\n" ); document.write( "*Note: Isoseles triangle has two equal sides.
\n" ); document.write( "Find the lengths of all sides: Let x represent to length of each of the legs.
\n" ); document.write( "The question states the following to be true about the perimeter:
\n" ); document.write( " $\"%28x-3%29+%2B+x+%2Bx+=36cm\"$ (x-3) being the length of the base.
\n" ); document.write( ".
\n" ); document.write( " $\"3x-3+=+36cm\"$
\n" ); document.write( " $\"3x=+39cm\"$
\n" ); document.write( " $\"x+=+13cm\"$ Base = (x-3) Base is 10cm, the other two sides are each 13 cm.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
