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.
