sin(theta) = opposite/hypotenuse\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "sin(75) = x/16\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "16*sin(75) = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 16*sin(75)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 16*0.965925826289068\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 15.4548132206251\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the ladder reaches approximately 15.4548 feet up the wall.
