Hi there, \n" ); document.write( "Consider the road is a right \n" ); document.write( "angled triangle. \n" ); document.write( "Hypotenuse = 300 ft. \n" ); document.write( "Altitude = Opposite side. \n" ); document.write( "Using trigonometric ratios. \n" ); document.write( "Sin(x) = opposite/hypotenuse \n" ); document.write( "sin (45) = opposite/300 \n" ); document.write( "Opposite = 300 x tan(45) \n" ); document.write( "Oppsite = 300 \n" ); document.write( "So altitude climbed = 300 feet. \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
