Лента летучей змеи фиксируется на высоте 60 м. Если лента имеет угол 30 ° относительно земли, определите длину ленты в пространстве.

Irrelevant7 Если считать землю за катет, ленту за гиппотенузу, а высоту в 60 метров за второй катет, то в прямоугольном треугольнике напротив угла в 30° лежит катет равный половине гиппотенузы, отсюда следует что длина ленты змеи равна 60*2=120
