When finding cosθ=3√2 on a unit circle, what type of special right triangle or a ray is used?(1 point) Responses a horizontal ray from the origin a horizontal ray from the origin 30-60-90 triangle 30-60-90 triangle 45-45-90 triangle 45-45-90 triangle a vertical ray from the origin

Answer 1

To find cos(θ) = 3√2 on a unit circle, we need to recall that the unit circle has a radius of 1. The cosine value represents the x-coordinate of a point on the unit circle.

However, cos(θ) = 3√2 exceeds the maximum possible value of 1 that cosine can take on the unit circle, since 3√2 ≈ 4.24. This means there cannot be any angle θ for which cos(θ) is equal to 3√2 on the unit circle.

Therefore, it doesn't apply to any type of special right triangle or ray because the value itself is not valid within the context of the unit circle.

If the question is looking for a valid x-coordinate on the unit circle, cos(θ) must be between -1 and 1. If 3√2 were to be provided incorrectly, please check the value given.
