I know that the sides of an isosceles triangle are equal.
\n" ); document.write( "so, $\"2x+%2B+4+=+x+%2B+8\"$
\n" ); document.write( "Subtract $\"x\"$ from both sides
\n" ); document.write( " $\"x+%2B+4+=+8\"$
\n" ); document.write( " $\"x+=+4\"$
\n" ); document.write( "And, since the base is $\"5x+-+2\"$ ,
\n" ); document.write( "base = $\"5%2A4+-+2\"$
\n" ); document.write( "base = $\"18\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
