Answer 1

Abigail Nelson

Matthew Carter

Given an angle of 120 degrees, determine which quadrant it lies in on the unit circle.

Step 1: Recognize that the unit circle is divided into 4 quadrants:
Quadrant I: 0° to 90°
Quadrant II: 90° to 180°
Quadrant III: 180° to 270°
Quadrant IV: 270° to 360°.

Step 2: Since 120° is between 90° and 180°, it lies in Quadrant II.

Answer: Quadrant II

Answer 2

Alex Thompson

Olivia Lee

Given an angle of 240 degrees, determine which quadrant it lies in on the unit circle.

Step 1: Identify the ranges of each quadrant:
Quadrant I: 0° to 90°
Quadrant II: 90° to 180°
Quadrant III: 180° to 270°
Quadrant IV: 270° to 360°.

Step 2: Since 240° is between 180° and 270°, it lies in Quadrant III.

Answer: Quadrant III

Answer 3
