The correct Answer is:
To find the complement of the given angles, we will follow these steps: ### Step-by-Step Solution 1. **Understand the Concept of Complementary Angles**: - Complementary angles are two angles whose sum is 90 degrees. 2. **Identify the Angles**: - The angles given are \(34^\circ 27'\) and \(27^\circ\). 3. **Calculate the Complement of \(34^\circ 27'\)**: - We need to find the complement by subtracting \(34^\circ 27'\) from \(90^\circ\). - First, we can express \(90^\circ\) as \(89^\circ 60'\) (since \(1^\circ = 60'\)). - Now perform the subtraction: \[ 90^\circ - 34^\circ 27' = 89^\circ 60' - 34^\circ 27' \] 4. **Subtract the Minutes**: - Subtract the minutes: \[ 60' - 27' = 33' \] 5. **Subtract the Degrees**: - Subtract the degrees: \[ 89^\circ - 34^\circ = 55^\circ \] 6. **Combine the Results**: - Therefore, the complement of \(34^\circ 27'\) is: \[ 55^\circ 33' \] 7. **Calculate the Complement of \(27^\circ\)**: - Now, we find the complement of \(27^\circ\): - Again, subtract from \(90^\circ\): \[ 90^\circ - 27^\circ = 63^\circ \] - Since there are no minutes involved, the complement is simply: \[ 63^\circ \] ### Final Answers: - The complement of \(34^\circ 27'\) is \(55^\circ 33'\). - The complement of \(27^\circ\) is \(63^\circ\).
