Решение 2 rus. №3.15 (с. 49)
Для решения этой задачи используется теорема о сумме углов треугольника. Согласно этой теореме, сумма всех трех внутренних углов любого треугольника всегда равна $180^\circ$.
Следовательно, чтобы найти неизвестный угол, нужно из $180^\circ$ вычесть сумму двух известных углов.
1) 50° и 30°
Сначала найдем сумму двух известных углов:
$50^\circ + 30^\circ = 80^\circ$
Теперь найдем неизвестный третий угол, вычтя полученную сумму из $180^\circ$:
$180^\circ - 80^\circ = 100^\circ$
Ответ: $100^\circ$.
2) 40° и 75°
Найдем сумму двух известных углов:
$40^\circ + 75^\circ = 115^\circ$
Вычислим третий угол:
$180^\circ - 115^\circ = 65^\circ$
Ответ: $65^\circ$.
3) 60° и 80°
Найдем сумму двух известных углов:
$60^\circ + 80^\circ = 140^\circ$
Вычислим третий угол:
$180^\circ - 140^\circ = 40^\circ$
Ответ: $40^\circ$.
4) 25° и 120°
Найдем сумму двух известных углов:
$25^\circ + 120^\circ = 145^\circ$
Вычислим третий угол:
$180^\circ - 145^\circ = 35^\circ$
Ответ: $35^\circ$.
