Odpowiedź:
a = 6cm
b = 4 cm
c² = a² + b²
c² = 36cm² + 16cm²
c² = 52cm²
c² = 4×13 cm²
[tex]c = 2 \sqrt{13} cm[/tex]
sin alfa =
[tex] \frac{6}{2 \sqrt{13} } = \frac{3 \sqrt{13} }{13} [/tex]
cos alfa =
[tex] \frac{4}{2 \sqrt{13} } = \frac{2 \sqrt{13} }{13} [/tex]
tg alfa =
[tex] \frac{6}{4} = \frac{3}{2} = 1.5[/tex]
sin beta = cos alfa
cos beta = sin alfa
tg beta =
[tex] \frac{4}{6} = \frac{2}{3} [/tex]
