\n" ); document.write( "The sides containing the right angle
\n" ); document.write( "One side is the distance and the other side is the height
\n" ); document.write( "tan(15°) = height / distance from cliff
\n" ); document.write( "tan(15°) = height / 1000
\n" ); document.write( "height = 1000 * tan(15°)
\n" ); document.write( "= 1000 * 0.26794919243
\n" ); document.write( "267.95 meters is the height (rounded).         ANSWER\r
