6) Fill in the trigonometric functions for angles B and M in triangle BCM, where C is the right angle.

Решение:

Для треугольника BCM (угол C = 90°):

• sin B = \(\frac{CM}{BM}\)
• cos B = \(\frac{BC}{BM}\)
• tg B = \(\frac{CM}{BC}\)
• sin M = \(\frac{BC}{BM}\)
• cos M = \(\frac{CM}{BM}\)
• tg M = \(\frac{BC}{CM}\)
