Final answer:
The angle complementary to 245° is 135°.
Step-by-step explanation:
The correct answer is d) 135°.
Complementary angles are angles that add up to 90 degrees. So, to find the complementary angle to 245 degrees, we subtract 245 degrees from 90 degrees:
90° - 245° = - 155°
Since we can't have negative angles, we add 180 degrees:
-155° + 180° = 25°
Therefore, 245° is complementary to 135°.
