Hi, I have a question which has been giving me some grief. Any help would be greatly appreciated.
The old-style Kit-Kat bar allowed for a saving of resources and costs in the size of the foil wrapping. The bar was offset on an angle of approx 21 degrees.
A given rectangular bar of chocolate is a cm by b cm, placed in a background rectangle ( c cm by d cm).
a= 12cm, b=8cm
Find the angle of offset, and find the length and width of the rectangular wrapping paper.
EDIT: For the purpose of this question, assume that the chocolate bar is flat.
