Question

2×9(90)÷3cos09+22=??

Answer 1

Ответ:

540cos(9)+22

Пошаговое объяснение:

2*9*90:3cos(9)+22 = 2*3*90cos(9)+22 = 540cos(9)+22

Answer 2

To solve the given equation, let's break it down step by step:

1. First, evaluate the cosine term: cos(09) = cos(9 degrees). Since cos(9 degrees) is a constant value, we'll assume it equals approximately 0.98768834059 (rounded to 11 decimal places).

2. Next, perform the multiplication: 2 × 9 = 18.

3. Now, perform the multiplication within the parentheses: 18(90) = 1620.

4. Divide the result from step 3 by 3: 1620 ÷ 3 = 540.

5. Multiply the cosine value from step 1 by 540: 0.98768834059 × 540 = 533.3333333646 (rounded to 10 decimal places).

6. Add 22 to the result from step 5: 533.3333333646 + 22 = 555.3333333646 (rounded to 10 decimal places).

Therefore, the final result of the given equation 2×9(90)÷3cos09+22 is approximately 555.3333333646.
