\n" ); document.write( "The sum of the three interior angles of any triangle is 180 so
\n" ); document.write( ".
\n" ); document.write( "Let x = measure of third angle
\n" ); document.write( "then
\n" ); document.write( "x + 54 + 54 = 180
\n" ); document.write( "x + 108 = 180
\n" ); document.write( "x = 180-108
\n" ); document.write( "x = 72 degrees
