Answer 1

2sinx-1=0
2sinx=1                                                                                                              
sinx=1/2                                                                                                                    
x=30
сначала( -1) переносиш в правую сторону уравнения, знак меняется на +          потом находим чему равно sinx, и по таблице находим, что 1/2 - это   sin30                                                                                             

Answer 2

Solving the Equation 2sin(x) - 1 = 0

To solve the equation 2sin(x) - 1 = 0, we can follow these steps:

1. Isolate the Term with the Sine Function: Add 1 to both sides of the equation to isolate the term with the sine function: ``` 2sin(x) = 1 ```

2. Solve for sin(x): Divide both sides by 2 to solve for sin(x): ``` sin(x) = 1/2 ```

3. Find the Angle x: We need to find the angles whose sine is 1/2. This can be done using the inverse sine function, also known as arcsin or sin^(-1). The angles that satisfy sin(x) = 1/2 are 30 degrees and 150 degrees (in the interval 0 to 360 degrees).

Therefore, the solutions for the equation 2sin(x) - 1 = 0 are: - x = 30 degrees - x = 150 degrees

So, the equation is satisfied when x is 30 degrees or 150 degrees.
