Question

Найти значение sin 31° и tg 29°

Answer 1

Sin30 - 1/2
31 чуть больше, может быть около 0,51
cos30 - sqrt(3)/2 ~ 0,866
tg(30)~1/2/0,866=0,577
tg(29) чуть меньше, около 0,554

Answer 2

To find the values of sine (sin) 31° and tangent (tg) 29°, we can use a scientific calculator or a trigonometric table. However, since you've asked for the values, here they are:

sin 31° ≈ 0.515 (rounded to three decimal places)

tg 29° ≈ 0.554 (rounded to three decimal places)

Remember that trigonometric functions often involve irrational numbers, and these values have been rounded for convenience. In more precise calculations, one would use the exact values.
