\r\n" );
document.write( "The kite is at point K.  Your hand is at point H.\r\n" );
document.write( "\r\n" );
document.write( "I will assume you are holding the string 5 feet above the ground\r\n" );
document.write( "at point H.  If that's not your height change it to your height.\r\n" );
document.write( "\r\n" );
document.write( "We want to find JK and then we'll add 5 feet to that.\r\n" );
document.write( "\r\n" );
document.write( "JK is the opposite side of the 50° angle in right triangle HJK.  \r\n" );
document.write( "The kite string HK = 50 feet is the hypotenuse of right triangle HJK.\r\n" );
document.write( "\r\n" );
document.write( "The trig ratio that involves the opposite side and the hypotenuse\r\n" );
document.write( "is the sine, which is \r\n" );
document.write( "\r\n" );
document.write( "sin(50°) = \r\n" );
document.write( "\r\n" );
document.write( "sin(50°) = \r\n" );
document.write( "\r\n" );
document.write( "Multiply both sides by 50\r\n" );
document.write( "\r\n" );
document.write( "50sin(50°) = JK\r\n" );
document.write( "\r\n" );
document.write( "50(.7660444431) = JK\r\n" );
document.write( "38.30222216 = JK\r\n" );
document.write( "\r\n" );
document.write( "So adding your holding height, (between J and the ground, which is\r\n" );
document.write( "also 5 feet, gives 43.30222216 feet.  Round to however many decimal\r\n" );
document.write( "places you were told to round.  To the nearest foot is 43 feet.\r\n" );
