To find the complement of an angle, subtract the given angle from 90 degrees.
Given angle: 78 degrees 43 seconds
First, convert the seconds to minutes:
43 seconds ÷ 60 = 0.717 minutes
Now, convert the given angle into decimal degrees:
78 degrees + 0.717 minutes ÷ 60 = 78.012 degrees
Next, subtract the decimal degrees from 90:
90 degrees - 78.012 degrees ≈ 11.988 degrees
Therefore, the complement of the angle 78 degrees 43 seconds is approximately 11 degrees 59 minutes 17 seconds.
