Answer:
Quadrant 1: 36°
Quadrant 2: 144°
Quadrant 3 (Given): 216°
Quadrant 4: 324°
Step-by-step explanation:
A 216° angle in standard position has its terminal side in quadrant 3 since 216° is between 180° and 270°.
216° - 180° = 36°
The reference angle for 216° is 36°
Quadrant 1: 36°
Quadrant 2: 180° - 36° = 144°
Quadrant 3 (Given): 216°
Quadrant 4: 360° - 36° = 324°
