Zad. 5
[tex]6^2+8^2=|AB|^2\\36+64 = |AB|^2\\|AB|^2=100\\|AB| = 10\\sin\alpha = \frac{6}{10} = \frac{3}{5}\\cos\alpha = \frac{8}{10} = \frac{4}{5}\\tg\alpha = \frac{6}{8} = \frac{3}{4}[/tex]
Zad. 6
[tex]\alpha = 42\\c = 34\\sin\alpha = \frac{a}{34}\\sin42 = \frac{a}{34}\\0,6691 = \frac{a}{34} /*34\\22,7494 = a\\a = 22,75m[/tex]
Odp. Wysokosc komina to 22,75m
