Answer:
Step-by-step explanation:
16° remains 16° because it's already within the 0° to 360° range.
420° is 60° more than 360°. So, 420° converts to 60°.
For the next set:
180° remains 180° as it's within the 0° to 360° range.
210° remains 210° as well because it's also within the 0° to 360° range.
