You can put this solution on YOUR website!
The angle $\"+2x+-+40+\"$ must be positive, so $\"+x+%3E+20+\"$
\n" ); document.write( "If $\"+x+%3E+20+\"$ , The other 2 angles will be greater than
\n" ); document.write( " $\"+2x+-+40\"$
\n" ); document.write( "Also the sum of the angles must be 180 degrees
\n" ); document.write( " $\"+3x+%2B+x+%2B+10+%2B+2x+-+40+=+180+\"$
\n" ); document.write( " $\"+6x+-+30+=+180+\"$
\n" ); document.write( " $\"+6x+=+210+\"$
\n" ); document.write( " $\"+x+=+35+\"$
\n" ); document.write( " $\"+x+%2B+10+=+45+\"$
\n" ); document.write( " $\"+3x+=+105+\"$
\n" ); document.write( " $\"+2x+-+40+=+30+\"$ This is the smallest \n" ); document.write( "

\n" );
