Odpowiedź:
Szczegółowe wyjaśnienie:
a)
[tex]sin\alpha=\frac{y}{z} \\\cos\alpha = \frac{x}{z} \\tg\alpha = \frac{y}{x}[/tex]
[tex]sin\beta =\frac{x}{z} \\cos\beta =\frac{y}{z} \\tg\beta = \frac{x}{y}[/tex]
b)
[tex]sin\alpha= \frac{c}{b} \\cos\alpha= \frac{a}{b} \\tg\alpha = \frac{c}{a}[/tex]
[tex]sin\beta = \frac{a}{b} \\cos\beta = \frac{c}{b} \\tg\beta = \frac{a}{c}[/tex]
c)
[tex]sin\alpha = \frac{l}{k} \\cos\alpha = \frac{m}{k} \\tg\alpha = \frac{l}{m}[/tex]
[tex]sin\beta = \frac{m}{k} \\cos\beta = \frac{l}{k} \\tg\beta = \frac{m}{l}[/tex]
