Answer:
No student is wrong.
Step-by-step explanation:
No student is wrong. Coterminal angles are angles with same initial side and terminal side. Coterminal angles θc of angle θ and can be found by
[tex]\theta_{c}=\theta \pm 360[/tex]
If θ =60°
Coterminal angles would be:
[tex]\theta_{c}=60 \pm 360\\\theta_{c}=-300 \quad and\quad 420[/tex]
