\n" ); document.write( "\n" ); document.write( "Definition: Complementary angles are the angles whose sum is \"90\" degrees
\n" ); document.write( "
\n" ); document.write( "let the angle be \"x\" (degrees) \r
\n" ); document.write( "\n" ); document.write( "complementary angle will be \"4x\"\r
\n" ); document.write( "\n" ); document.write( " \"4x%2Bx=90\" (by definition)
\n" ); document.write( "\"+5x=90\"
\n" ); document.write( " \"x=90%2F5\"
\n" ); document.write( " \"x=18\" (degrees) \r
\n" ); document.write( "\n" ); document.write( " The required angle is \"x=18\" degrees and the complementary angle\"4x=72\" degrees.
\n" ); document.write( "
\n" );
