Select all that are measures of angles that are coterminal with a –50° angle.

Coterminal angles differ by a whole-number multiple of 360°. Starting with –50°, subtracting 720° gives –770° (A), subtracting 360° gives –410° (C), and adding 360° or 720° gives 310° (E) or 670° (H). The other choices do not differ from –50° by a multiple of 360°.
