Question

3) sin30° - 3tg45°;пжжж​

Answer 1

Ответ:

$\sin( {30}^{0} ) - 3 \tan( {45}^{0} ) = \frac{1}{2} - 3 \times 1 = \frac{1}{2} - 3 = - \frac{5}{2}$

Answer 2

Let's calculate the expression step by step:

1. sin(30°):

sin(30°) = 1/2

2. tan(45°):

tan(45°) = 1

Now, let's plug these values into the expression:

sin(30°) - 3 * tan(45°) = (1/2) - 3 * 1 = 1/2 - 3 = -5/2

So, the result of the expression is -5/2.
