Unghiurile complementare sunt 2 unghiuri adacente care au suma masurilor 90*.

Unghiul AOB complementul lui unghiului BOC.
Care este masura lui AOB^ daca m(BOC^)= 59* 59' 59''? Wink

1^\circ=60'=60\cdot 60''=3600''

In problema noastra
59''+1''=60"=1'
59'+1'=60'=1^\circ
59^\circ+1^\circ=60^\circ
90^\circ-60^\circ=30^\circ

Deci complementul este 30^\circ +1''.

Numerele de la unghiuri seamana cu niste numere in baza 60 in loc de baza 10 Very Happy.

Cum se pot scrie minutele si secundele in LaTeX? Vad ca nu apar deloc cand le scrii cu TeX.

90*- 59*59'59"= 89*59'60"- 59*59'59" = 30*0'1"= 30*1"
