Sixty-six * * * coins with a total value of 17 yuan. How many coins are there in each?
Let 1 yuan x, Pentagon (66-X),1* x+1/2 (66-x) =17, X=-32? Are you sure this question is correct?
If there is no 1 block, it is all 50 angles, and 50 angles are at most 17*2=34. How can there be 66 yuan? So this question is wrong, or you typed the number wrong.
