Решение 2 rus. №2.44 (с. 64)

Пусть в заданном прямоугольном треугольнике $a$ и $b$ — катеты, а $c$ — гипотенуза. По условию нам дан катет $b$ и прилежащий к нему острый угол $\alpha$. Это означает, что угол $\alpha$ находится между катетом $b$ и гипотенузой $c$. Второй острый угол, противолежащий катету $b$, обозначим как $\beta$, а прямой угол — $\gamma$.

Второй катет $a$

Искомый катет $a$ является противолежащим углу $\alpha$, а данный катет $b$ — прилежащим. Используя определение тангенса острого угла в прямоугольном треугольнике:
$\tan(\alpha) = \frac{\text{противолежащий катет}}{\text{прилежащий катет}} = \frac{a}{b}$
Отсюда выражаем катет $a$:
$a = b \cdot \tan(\alpha)$
Ответ: $a = b \cdot \tan(\alpha)$

Гипотенуза $c$

Катет $b$ прилежит к углу $\alpha$, а $c$ — гипотенуза. Используя определение косинуса острого угла:
$\cos(\alpha) = \frac{\text{прилежащий катет}}{\text{гипотенуза}} = \frac{b}{c}$
Отсюда выражаем гипотенузу $c$:
$c = \frac{b}{\cos(\alpha)}$
Ответ: $c = \frac{b}{\cos(\alpha)}$

Второй острый угол $\beta$

Сумма острых углов в прямоугольном треугольнике равна $90^\circ$. Следовательно:
$\alpha + \beta = 90^\circ$
Отсюда выражаем угол $\beta$:
$\beta = 90^\circ - \alpha$
Ответ: $\beta = 90^\circ - \alpha$

Прямой угол $\gamma$

По определению, в прямоугольном треугольнике один из углов является прямым.
$\gamma = 90^\circ$
Ответ: $\gamma = 90^\circ$
