A boat has to cross a river.
\n" ); document.write( "It crosses the river by making an angle of 60 deg with the bank of the river due to stream of the river and travels a distance of 600m to reach the another side of the river.
\n" ); document.write( "What is the width of the river?
\n" ); document.write( ":
\n" ); document.write( "Draw this out, see that it forms a right triangle, Side opposite the 60degree angle, is the width of the river (w), the hypotenuse is the path of the boat, 600m
\n" ); document.write( ":
\n" ); document.write( "sin(60) = $\"w%2F600\"$
\n" ); document.write( ".866*600 = w
\n" ); document.write( "w = 519.6 m across
\n" ); document.write( " \n" ); document.write( "

\n" );
