Answer 2

118 10' 48''

145.92 ---> 145 55' 12''

Answer 3

1 degree contains 60 minutes. 1 minute contains 60 seconds. So 1 second is 1/3600 of a degree.
145.92º is 145º and 0.92 of a degree. Multiply 0.92 deg *60 min/deg= 55.2 minutes
We have 55 minutes plus 0.2 minutes. Change 0.2 min to seconds by multiplying
0.2 min * 60 sec/min= 12 seconds
Final answer:
145º 55' 12"
