Please help AND NO LINKS OR U WILL BE REPORTED! Identify the reference angle ∅ for each given angle, Ф.

When Ф = 300°, ∅=degrees
When Ф = 225°, ∅= degrees
When Ф = 480°, ∅=degrees
when Ф = -210°, ∅= degrees

See below for answers

Step-by-step explanation:

300° is in Quadrant IV, so its reference angle is 360°-300°=60°

225° is in Quadrant III, so its reference angle is 225°-180°=45°

480°=120° is in Quadrant II, so its reference angle is 180°-120°=60°

-210°=150° is in Quadrant II, so its reference angle is 180°-150°=30°
