Помогите срочно 2cos0°-4sin30°

Answer 1

2 * (4 * 0.5 ) = 2-2=0

Answer 2

I can help you with your math problem.

To solve 2cos0°-4sin30°, you need to use the values of the trigonometric functions at the given angles. Cosine of 0 degrees is 1, and sine of 30 degrees is 0.5. Therefore, you can substitute these values into the expression and simplify:

$$2cos0°-4sin30° = 2 \times 1 - 4 \times 0.5 = 2 - 2 = 0$$

The answer is 0. I hope this helps you. If you need more explanation, you can check out some online resources that explain trigonometry, such as [this one](https://online-otvet.ru/algebra/5ceab22e96f4e19a297ed459).
