It looks like you're asking to **select the pair of angles that are coterminal**. Coterminal angles are angles that share the same terminal side when drawn in standard position, differing by full rotations of $$360^\circ$$.

Let's evaluate each pair:

1. **45° and 225°**
   - Difference: $$225° - 45° = 180°$$
   - Not coterminal (they are **supplementary angles**).

2. **-50° and 150°**
   - Difference: $$150° - (-50°) = 200°$$
   - Not coterminal.

3. **60° and 300°**
   - Difference: $$300° - 60° = 240°$$
   - Not coterminal.

4. **-70° and 290°**
   - To check coterminality:
     $$
     -70° + 360° = 290°
     $$
   - Since adding $$360°$$ to $$-70°$$ gives $$290°$$, these angles are **coterminal**.

5. **90° and -90°**
   - Difference: $$90° - (-90°) = 180°$$
   - Not coterminal (they are **opposite angles**).

**Conclusion:**  
The pair **$$-70^\circ$$ and $$290^\circ$$** are coterminal angles.
The pair $$-70^\circ$$ and $$290^\circ$$ are coterminal angles.
