Determine whether 420° and 7π/3 radians are coterminal. Provide the arithmetic justification in degrees.

Yes; both reduce to 60°, so they are coterminal.

No; because 420° is greater than 360° and 7π/3 cannot be larger than 2π.

Yes; convert 420° to radians to 7π/6.

No; because one is written in degrees and the other in radians.
