Question

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

Answer 1

Answer:

$\boxed{(-\frac{\sqrt{3}}{2}, \frac{1}{2})}$

Step-by-step 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 (see attachment).

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