Find the measure of (a) the complement and (b) the supplement of an angle with the given measure. See Examples 1 and 3. 50° 40' 50"

Guida verificata passo dopo passo

Understand the definitions: The complement of an angle is what, when added to the angle, equals 90 degrees, and the supplement of an angle is what, when added to the angle, equals 180 degrees.

Convert the given angle 50° 40' 50" into a consistent format if needed, but since the problem is in degrees, minutes, and seconds, we can work directly with these units.

To find the complement, subtract the given angle from 90° 0' 0" using the subtraction of degrees, minutes, and seconds carefully:

\[ \text{Complement} = 90^\circ 0' 0'' - 50^\circ 40' 50'' \]

To find the supplement, subtract the given angle from 180° 0' 0" similarly:

\[ \text{Supplement} = 180^\circ 0' 0'' - 50^\circ 40' 50'' \]

Perform the subtraction step-by-step, borrowing minutes and seconds as necessary to handle the subtraction of minutes and seconds correctly.

Angle Measurement in Degrees, Minutes, and Seconds

Angles can be measured in degrees (°), minutes ('), and seconds ("). One degree equals 60 minutes, and one minute equals 60 seconds. Properly converting and subtracting these units is crucial when calculating complements and supplements of angles given in this format.
