Identify which of the following pairs of angles are complementary.a)65...
**Complementary Angles:**
Complementary angles are a pair of angles whose measures add up to 90 degrees. In other words, when you add the measures of two complementary angles, the sum will equal 90 degrees.
**Explanation:**
Let's analyze each pair of angles given and determine if they are complementary or not.
a) 65°, 115°: The sum of these angles is 65° + 115° = 180°, which is greater than 90°. Therefore, these angles are not complementary.
b) 130°, 50°: The sum of these angles is 130° + 50° = 180°, which is greater than 90°. Therefore, these angles are not complementary.
c) 63°, 27°: The sum of these angles is 63° + 27° = 90°. This sum is exactly 90°, which means these angles are complementary.
d) 112°, 68°: The sum of these angles is 112° + 68° = 180°, which is greater than 90°. Therefore, these angles are not complementary.
Therefore, the pair of angles that is complementary is **c) 63°, 27°**.

b) 130°, 50°: The sum of these angles is 130° + 50° = 180°, which is greater than 90°. Therefore, these angles are not complementary.
c) 63°, 27°: The sum of these angles is 63° + 27° = 90°. This sum is exactly 90°, which means these angles are complementary.
d) 112°, 68°: The sum of these angles is 112° + 68° = 180°, which is greater than 90°. Therefore, these angles are not complementary.
Therefore, the pair of angles that is complementary is **c) 63°, 27°**.
