Let the required angle be x.\r
\n" ); document.write( "\n" ); document.write( "as per given instructions, x =2(90-x)
\n" ); document.write( "here 90-x means compliment of x.\r
\n" ); document.write( "\n" ); document.write( "thus solving the above equation we get,\r
\n" ); document.write( "\n" ); document.write( "x=180-2x
\n" ); document.write( "thus, 3x=180
\n" ); document.write( "thus, x=180/3
\n" ); document.write( "thus x =60\r
\n" ); document.write( "\n" ); document.write( "so the required angle is 60 degree.
\n" ); document.write( "
