Questão de PET - (ENEM) Sobre o sistema cartesiano considera-se uma malha formada por circunferências

8 – (ENEM) Sobre o sistema cartesiano considera-se uma malha formada por circunferências de raios com medidas dadas por números naturais e por 12 semirretas com extremidades na origem, separadas por ângulos de π/6 rad, conforme a figura. Suponha que os objetos se desloquem apenas pelas semirretas e pelas circunferências dessa malha, não podendo passar pela origem (0, 0).

Questão de PET - (ENEM) A rosa dos ventos é uma figura que representa oito sentidos

7 – (ENEM) A rosa dos ventos é uma figura que representa oito sentidos, que dividem o círculo em partes iguais. Uma câmera de vigilância está fixada no teto de um shopping e sua lente pode ser direcionada remotamente, através de um controlador, para qualquer sentido. A lente da câmera está apontada inicialmente no sentido Oeste e o seu controlador efetua três mudanças consecutivas, a saber:

• 1a mudança: 135° no sentido anti-horário;

• 2a mudança: 60° no sentido horário;

• 3a mudança: 45° no sentido anti-horário.

Após a 3a mudança, ele é orientado a reposicionar a câmera, com a menor amplitude possível, no sentido Noroeste (NO) devido a um movimento suspeito de um cliente. Qual mudança de sentido o controlador deve efetuar para reposicionar a câmera?

a) 75° no sentido horário.

b) 105° no sentido anti-horário.

c) 120° no sentido anti-horário.

d) 135° no sentido anti-horário.

e) 165° no sentido horário.
