document.write( "You have a right-angled triangle with the angle of 45 degrees at the base - \r\n" );
document.write( "\r\n" );
document.write( "so, this right-angled triangle has two congruent acute angles at the base,\r\n" );
document.write( "\r\n" );
document.write( "i.e. is isosceles right angled triangle.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the height of the tower is 200 feet, i.e. the same length as the horizontal \r\n" );
document.write( "distance to the tower.\r\n" );
