Question

Enter the coordinates of the point on the unit circle at the given angle. 150 degrees. please help!

Answer 1

Answer: This coordinate pair is (-√3/2, 1/2).

Explanation:

Use the unit circle to locate the angle measure of 150° (or 5π/6 radians) and use the coordinate pair listed by the value.

Answer 2

`\boxed{(-(√(3))/(2), (1)/(2))}`

Explanation:

Method 1: Using a calculator instead of the unit circle

The unit circle gives coordinates pairs for the cos and sin values at a certain angle. Therefore, if an angle is given, use a calculator to evaluate the functions at cos(angle) and sin(angle).

Method 2: Using the unit circle

Use the unit circle to locate the angle measure of 150° (or 5π/6 radians) and use the coordinate pair listed by the value.

This coordinate pair is (-√3/2, 1/2).
