\r\n" );
document.write( "Here are the rules you need for solving such problems:\r\n" );
document.write( "\r\n" );
document.write( "1. Observe which side of the right triangle you are given.\r\n" );
document.write( "2. Observe which side of the right triangle you want to find.\r\n" );
document.write( "3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From these three pick the trig function that has as a numerator\r\n" );
document.write( "and denominator the side you are given and also the side you \r\n" );
document.write( "want to find.\r\n" );
document.write( "\r\n" );
document.write( "You are given 44ft, which is the ADJACENT side of the angle 65°\r\n" );
document.write( "You want to find the height of the buiding h, which is the OPPOSITE \r\n" );
document.write( "side of angle 65°.\r\n" );
document.write( "\r\n" );
document.write( "Therefore pick the TANGENT, because it is the only one of the \r\n" );
document.write( "three that has both what side you are given and what side you \r\n" );
document.write( "want to find.\r\n" );
document.write( "\r\n" );
document.write( "Solution:\r\n" );
document.write( "\r\n" );
document.write( "      tan(65°) = \r\n" );
document.write( "\r\n" );
document.write( "Multiply both sides by 44\r\n" );
document.write( "\r\n" );
document.write( "   44·tan(65°) = h\r\n" );
document.write( "\r\n" );
document.write( "44·2.144506921 = h  \r\n" );

document.write( "    94.3583045 = h\r\n" );
