\n" ); document.write( "\n" ); document.write( "This problem is about a triangle  STR  inscribed into a circle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This triangle has side  SR  as a diameter of the circle - - - hence,  the triangle is a right-angled triangle
\n" ); document.write( "with the right angle  T  opposite to side  SR.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Also,  the triangle has leg  ST  one half of the hypotenuse  SR - - - hence,  it is  30-60-90  degrees triangle.\r
