I have a parallelogram (rv lot)45 feet by 30 feet with angle of 60 degrees..question is...will my rv of 40 feet by 10 feet fit on lot without crossing boundries?
\n" ); document.write( "-------------------------
\n" ); document.write( "Draw the picture of the rv in the parallelogram.
\n" ); document.write( "The back of the rv is the base of an equilateral
\n" ); document.write( "triangle with 60 degree angles and sides of 10 ft.
\n" ); document.write( "------------
\n" ); document.write( "The triangle with the 120 degree angle has sides
\n" ); document.write( "of 20 ft and 45 ft.
\n" ); document.write( "Determine whether the 3rd side is >=40 ft. by
\n" ); document.write( "using the Law of Cosines
\n" ); document.write( "-----------
\n" ); document.write( "x^2 = 20^2 + 45^2 -2*20*45*cos120 = 3325
\n" ); document.write( "x = 57.66 ft.
\n" ); document.write( "-----------------
\n" ); document.write( "Yes your 40 foot long rv will fit in the lot.
