Answer:
Step-by-step explanation:
Coterminal angles are defined as angles which have the same terminal side.
To find coterminal angles, we just need to sum or subtract 360° from the first angle.
For example, the angle 400° is coterminal with 40°, beacuse 40° + 360° = 400°.
Therefore, the right asnwer is A. That pair of angles are coterminal angles.
On the other hand, the other choices don't show coterminal angles, because
-580 + 360 = -220°
-140 + 360 = 220°
140 + 360 = 500°
The pair of angles are coterminal with 220 degrees are -140 degrees and 580 degrees.
The correct answer is option C
Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.
The pair of angles are coterminal with 220 degrees
220° + 360° = 580°
220° - 360° = -140°
Therefore, the pair of angles are coterminal with 220 degrees are -140 degrees and 580 degrees.
