$\"sin%28x%29=+-0.8\"$
\n" ); document.write( " $\"x=-53.1\"$ degrees
\n" ); document.write( "and by identity, 180-x, also solves,
\n" ); document.write( " $\"180-x=180-%28-53.1%29=233.1\"$ degrees.
\n" ); document.write( "We'll make both values positive.
\n" ); document.write( " $\"x=-53.1%2B360=306.9\"$ and $\"x=233.1\"$
\n" ); document.write( "To change from degrees to radians use the conversion factor
\n" ); document.write( " $\"%282%2Api%29%2F360\"$ radians/degree
\n" ); document.write( " $\"x=306.9%2A%282%2Api%29%2F360\"$ radians
\n" ); document.write( " $\"x=5.36\"$ radians
\n" ); document.write( " $\"x=233.1%2A%282%2Api%29%2F360\"$ radians
\n" ); document.write( " $\"x=4.07\"$ radians
\n" ); document.write( " \n" ); document.write( "
