\n" ); document.write( "size of minor arc AB.
\n" ); document.write( "
With center O, and altitude OD drawn from center to chord, we get cos ∡OAD = \"matrix%281%2C5%2C+A%2FH%2C+%22=%22%2C+8%2F12%2C+%22=%22%2C+48.19%5Eo%29\"
\n" );
document.write( "∡OBD also = 48.19o
\n" );
document.write( "Therefore, central ∡AOB = 180 - 2(48.19o) = 180 - 96.38o = 83.62o
\n" );
document.write( "From this, we can see that
