Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that <J and <K are complementary, and that the measure of <J is 48 degrees, 26 minutes, 8 seconds. what is the measure of <K.

It is unfortunate that measurement of angles, and time, has escaped the metric system.
Things would be so much easier.
K = 90° - 48° 26' 8"
= 89° 59' 60" - 48°26'8"
= 41° 33' 52"
Hint:
If you have a good scientific calculator, look for key labeled
D°M'S
it will do all your calculations in base 60
enter
90 DMS
-
48 DMS 26 DMS 8 DMS
=
and voila! there is your answer
btw, that same key can be used to do arithmetic of addition/subtraction of different times.
e.g. 5:12:45 + 4:55:12
= 10:07:57

The answer is 41 degrees and 52 seconds.... borrow 1 from the complementary 90 degrees and make it 89 degrees and 60 mins subract the 48 degrees and 8 seconds -48 26 mins 8 seconds
