document.write( "solve for the value of  “A” when sin A=3.5x and cosA=5.5x.\r\n" );
document.write( "Ans:\r\n" );
document.write( "Use the identity sin^2 A + cos^2 A = 1\r\n" );
document.write( "Substituting that sin A = 3.5*x and cos A = 5.5*x\r\n" );
document.write( "\"%283.5%2Ax%29%5E2+%2B+%285.5%5Ex%29%5E2+=+1\"\r\n" );
document.write( "\"12.25%2Ax%5E2+%2B+30.25%2Ax%5E2+=+1\"\r\n" );
document.write( "\"42.5%2Ax%5E2+=+1\"\r\n" );
document.write( "\"x%5E2+=+1%2F42.5+=+0.0235\"\r\n" );
document.write( "\"x+=+0.1533\"\r\n" );
document.write( "So, Sin A = \"0.1533+%2A+3.5+=+0.5365\"\r\n" );
document.write( "A = 32.45 degrees approx (from calculator)\r\n" );
