Consider the three points:
\n" ); document.write( "A=(2,1)
\n" ); document.write( "B=(6,3)
\n" ); document.write( "C=(9,7)\r
\n" ); document.write( "\n" ); document.write( "Determine the angle between AB and AC
\n" ); document.write( "

Side AB = c
\n" );
document.write( "Side AC = b
\n" );
document.write( "Side BC = a\r
\n" );
document.write( "\n" );
document.write( "Find the lengths of a, b, and c, using the given coordinate points and the distance formula. You want the angle between lines AB and AC, which is A
\n" );
document.write( "Therefore, use the following law of cosine formula to find angle A:
\n" );
document.write( ", or  \n" );
document.write( "

\n" );
