A. the figure at the right shows a long rectangular strip of paper, one corner of which has been folded over to meet the opposite edge, thereby creating a 30-degree angle. given the width of the strip is 12 inches, find the length of the crease.
b. instead of a 30-degree angle, suppose that the angle has an unspecified size t. use trigonometry to find the length of the crease, expressed in terms of t.
c. find the approximate value of t that makes the crease as short as it can be. restrict your attention to values of t that are less than 45 degrees. explain your method.
