Question

Tg альфа = sin альфа : cos альфа Sin =4\5 Cos =-3/5

Answer 1

Ответ:

4/5 ÷(-3/5 ) = -4/5 ÷3/5  = - 4/5 × 5/3  = - 4·5/5·3  = - 20/15  = - 4·5/3 ·5  = - 4/3  = - 1·3 + 1/3  = -1 целая 1/3

Answer 2

To find the value of tg(α) given sin(α) = 4/5 and cos(α) = -3/5, we can use the definition of tangent:

tg(α) = sin(α) / cos(α)

Plugging in the given values, we have:

tg(α) = (4/5) / (-3/5)

To divide by a fraction, we can multiply by its reciprocal:

tg(α) = (4/5) * (-5/3)

Multiplying across, we get:

tg(α) = -20/15

This can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:

tg(α) = -4/3

Therefore, tg(α) is equal to -4/3.
