Find the measure of (a) the complement and (b) the supplement of an angle with the given measure. See Examples 1 and 3. 14° 20'

검증된 단계별 안내
1
Understand the definitions: The complement of an angle is what, when added to the angle, equals 90°. The supplement of an angle is what, when added to the angle, equals 180°.
Convert the given angle 14° 20' into a decimal or keep it in degrees and minutes format for calculation. Remember that 1 degree = 60 minutes.
To find the complement, set up the equation: Complement + 14° 20' = 90°. Rearrange to find Complement = 90° - 14° 20'.
To find the supplement, set up the equation: Supplement + 14° 20' = 180°. Rearrange to find Supplement = 180° - 14° 20'.
Perform the subtraction carefully, handling the minutes properly (if minutes in the angle are greater than the minutes in 90° or 180°, borrow 1 degree = 60 minutes) to find the exact measures of the complement and supplement.

Complementary Angles

Complementary angles are two angles whose measures add up to 90 degrees. To find the complement of a given angle, subtract the angle's measure from 90°. This concept is essential for problems involving right angles and angle pairs.

Angle Measurement in Degrees and Minutes

Angles can be measured in degrees (°) and minutes ('). One degree equals 60 minutes. When performing calculations, convert minutes properly and carry over values when minutes exceed 60, ensuring accurate results in angle arithmetic.
