The tetrahedron is very special geometric shape in chemistry. The Periodic Table has four major areas that are called s,f,d,p blocks. It was recently discovered that those blocks, if ordered and proportioned in accordance with the quantum numbers, are simply the slices of regular tetrahedron. You can check it out at
ADOMAH Periodic Table Web site. -

I think it is acceptable to state the value of the angle to many figures ONCE, since the object of an encyclopedia is to give information accurately. Of course after the first time, the remaining mentions of the angle are rounded off to 1 or 2 figures after the decimal point.
Note also that the figures are correct and therefore really significant, since the calculation is mathematical and not based on any measurement.
