2x+10, x, (2x+10-10) are the three angles.
\n" ); document.write( "2x+10+x+2x+10-10=180
\n" ); document.write( "5x=180-10
\n" ); document.write( "5x=170
\n" ); document.write( "x=170/5
\n" ); document.write( "x=34 degrees for the second angle.
\n" ); document.write( "2*34+10=68+10=78 degrees for the first angle.
\n" ); document.write( "2*34+10-10=68 degrees for the third angle.
\n" ); document.write( "PROOF:
\n" ); document.write( "34+78+68=180
