At the top of each page, you must write your Student ID number (found on the cover sheets your teacher gave you), the problem number, and the page number in the format from 1 to 'n', where 'n' is the number of pages for the solution to that problem. For example: Student ID 123456 Problem 1 ...Problem 3. An equilateral triangle of side length is given. Suppose that equilateral triangles with side length 1 and with non-overlapping interiors are drawn inside , such that each unit equilateral triangle has sides parallel to , but with opposite orientation. (An example with is …1An alternative approach for students who know Euler's theorem is to simply notice '(220) = 219, where ' is the Euler phi function. Therefore 5219 1 (mod 220) and so 5219+20 520(mod 220). The hands-on proof gives a tad more; since 5 211 = 22, in fact 2 divides 5191, not just 220. 5. Created Date.
