Question

Gente me ajudem pelo amor de Deus (a perguntra esta na foto) :(

Answer 1

$sen = \frac{CO}{H}\\\\ sen\ 65\° = \frac{x}{9}\\\\ 0,91 = \frac{x}{9}\\\\ x = 0,91*9\\\\ \boxed{x =8,19}$

$tg = \frac{CO}{CA}\\\\ tg\ 65\° = \frac{x}{y}\\\\ 2,14 = \frac{8,19}{y}\\\\ y = \frac{8,19}{2,14}\\\\ \boxed{y =3,82}$

Answer 2

cos 65° = y / 90,42 * 9 = yy = 3,78 sen 65° = x /9 0,91 * 9 = xx = 8,19
