alleryTwo angles are complementary. One is 35 degrees. What is the other?
A35 degrees
B55 degrees
C65 degrees
D145 degrees
Answer & Solution
Correct answer: B. 55 degrees
1. Complementary angles add up to a right angle, which is 90 degrees.
2. Other angle = 90 - 35.
3. So the other angle is 55 degrees. The value 145 comes from using 180 by mistake.
