QuestionTrova cosβ,tanγ,sinδ\cos \beta, \tan \gamma, \sin \delta sapendo che sinα=35\sin \alpha = \frac{3}{5}.

Studdy Solution
Calcola sinδ\sin \delta. Poiché δ\delta è l'angolo complementare di γ\gamma, abbiamo:
sinδ=cosγ=cateto adiacenteipotenusa=45 \sin \delta = \cos \gamma = \frac{\text{cateto adiacente}}{\text{ipotenusa}} = \frac{4}{5}
Le soluzioni sono:
cosβ=35,tanγ=34,sinδ=45 \cos \beta = \frac{3}{5}, \quad \tan \gamma = \frac{3}{4}, \quad \sin \delta = \frac{4}{5}
