1. The problem states that three angles formed at the center of a circle add up to 360° because the total degrees around a point is 360°. 2. The given angles are 152°, 49°, and $x$°. 3. The formula to find $x$ is: $$x = 360 - (152 + 49)$$ 4. Calculate the sum inside the parentheses: $$152 + 49 = 201$$ 5. Substitute back: $$x = 360 - 201$$ 6. Simplify: $$x = 159$$ 7. Therefore, the value of $x$ is 159°. Note: Since 159° is not among the options, please verify the problem or options given.
