Kelly wants to cut her birthday cake into 20 equal pieces. If she uses all of the cake, what is the correct angle she needs to cut to make 20 equal pieces of cake?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
