You can put this solution on YOUR website!

complementary angles are angles whose measures sum to 90°
given: theta =25degrees 43 minutes 37 seconds

complementary angle is:
90° 0 minutes 0 seconds
-
25° 43 minutes 37 seconds
_____________________________________________ take one degree from 90° and convert to minutes: you will have 89°60 minutes
now take one minute from 60 minutes and convert to seconds: you will have 59minutes60 seconds
now subtract
89° 59 minutes 60 seconds
-
25° 43 minutes 37 seconds
_____________________________________________
64° 16 minutes 23 seconds
