since we have a right triangle, we know
\n" ); document.write( ":
\n" ); document.write( "sin(A) = BC / AC
\n" ); document.write( ":
\n" ); document.write( "we know sin(A) = (1/2) and BC = 8 inches, therefore
\n" ); document.write( ":
\n" ); document.write( "(1 / 2) = (8 / AC)
\n" ); document.write( ":
\n" ); document.write( "cross multiply the two fractions since they are equal
\n" ); document.write( ":
\n" ); document.write( "AC = 16 inches
