(22pt.) let u-{1,2,3,4,5) be the universal set, and let a 1,2,3), b = {2,3,4 (2,3,5). determine the following (show all steps) 1 and c a) find au (bnc), (aub)n c, and (au b) n (auc). which of these sets are equal? (b) find a-(b-c) and (a- b)-c. are these sets equal? c) find b' (start with the definition of the complement of a set)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
