2cos(x) + 1 = 0

cos(x) = -\frac{1}{2}

The basic angle for 1/2 is 60°, and cosines are negative in the first and third quadrant.

So, you take 180° - 60° = 120° to get the angle in the first quadrant, and 180° + 60° = 240° to get the angle in the third quadrant.

Since only 120° is an option, the answer is B.

Answer:

A. b2 – 4ac = 0

Step-by-step explanation:

Hey user☺☺

Option a is correct

Because the graph has only one solution.

As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.

Hope this will help☺☺
