Abstract

The article shows a solution of the problem B—I—3 of the 67th year of Mathematics olympiad. This solution is different  from the author's one and the golden ratio takes place in it in an interesting way. The link between the text of the problem and the golden ratio is not obvious and it can be used to prove that the rhombus in the problem assignment is a part of a regular pentagon.
