Algebra.Com's Answer #598427 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Consider that the rope to the tent \n" ); document.write( "is the hypotenuse of a right angled triangle. \n" ); document.write( "The distance of 1 metre on ground is the \n" ); document.write( "adjacent side of the triangle. \n" ); document.write( "Using trigonometric ratio:- \n" ); document.write( "Cosine = Adjacent/Hypotenuse \n" ); document.write( "Cosine 57 degrees = 1 metre/ Hypotenuse \n" ); document.write( "Therefore Hypotenuse (Length of rope) \n" ); document.write( "= 1 metre/ Cosine 57 degrees \n" ); document.write( "= 1.84 metres (2 decimal places) \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
