2) Fill in the trigonometric functions for angles K and P in triangle PRK, where R is the right angle.

Решение:

Для треугольника PRK (угол R = 90°):

• sin K = \(\frac{PR}{PK}\)
• cos K = \(\frac{RK}{PK}\)
• tg K = \(\frac{PR}{RK}\)
• sin P = \(\frac{RK}{PK}\)
• cos P = \(\frac{PR}{PK}\)
• tg P = \(\frac{RK}{PR}\)
