221.5584 ≈ 221.6
The closest answer is Option D, therefore it should be the correct answer.
Answer:
true
Step-by-step explanation:
Hello There!
I believe that the relationships that can help you solve this problem are that the angle is Complementary and Supplementary. It is complementary because within the angle, there is an angle that is 90°. It is also supplementary because the angle itself is 180° making the angle supplementary.
I hope this helps!
