What is the x-value at 60° ? Write as an exact value (no decimals).(1 point)

Answer 1

To find the x-value at an angle of 60°, we can refer to the unit circle. In the unit circle, the x-value corresponds to the cosine of the angle.

For \(60^\circ\):

\[ \text{cos}(60^\circ) = \frac{1}{2} \]

Therefore, the exact x-value at \(60^\circ\) is:

\[ \frac{1}{2} \]

Answer 2

What is the y-value at 240° ? Write your answer as an exact value (no decimals).(1 point)

Answer 3

To find the y-value at an angle of 240°, we use the unit circle. The y-value corresponds to the sine of the angle.

For \(240^\circ\):

\[ \text{sin}(240^\circ) = -\frac{\sqrt{3}}{2} \]

Therefore, the exact y-value at \(240^\circ\) is:

\[ -\frac{\sqrt{3}}{2} \]
