which of the following uses the special triangles on the unit circle to determine in degrees when cos0 = √3/2? you may assume that 0° ≤ 0 ≤ 180°
To determine when cos0 is equal to √3/2, we need to find the angle (in degrees) whose cosine value is equal to √3/2.
Using the special triangles on the unit circle, we find that cos60° = √3/2.
Since cosine function is an even function, cos(-60°) = cos60° = √3/2.
Therefore, when cos0 = √3/2, the angle in degrees can be 60° or -60°.
