It happens that $s^2$ and $\hat s^2$ are equal with 0.1% accuracy, thoughthey are split by radiative corrections and a natural estimate for theirdifference is 1%. This degeneracy occurs only for $m_t$ value close to$170\GeV$, so no deep physical reason can be attributed to it. However, anotherpuzzle of the Standard Model, the degeneracy of $s_\Eff^2$ and $s^2$, is notindependent of the previous one since a good physical reason exists for$s_\Eff^2$ and $\hat s^2$ degeneracy. We present explicit formulas which relatethese three angles.Comment: 10 pages, latex, 3 figures included; published on MPLA. A few  numerical estimates are improved; journal-ref is adde
