Which two values of x satisfy the equation square root 3-2cos x = 2?
Andrei [34K]

Answer: x=2π/3 and x=4π/3

Step-by-step explanation:

The equation we have is \sqrt{3-2cosx} =2. All we have to do is get cosine alone to find the 2 values of x.

3-2cosx=4\\-2cosx=1\\cosx=-\frac{1}{2}

Now that we have our cosine left, we can use our unit circle to figure out when does cosx=-1/2. Cosine is the x value of the coordinate.

x=2π/3

x=4π/3
