Use the conversions:
60' = 1 degree
60" = 1'
---------------------
First, I can say:
94 degrees = 93 degrees + 60'
Next, I can say:
94 degrees = 93 degrees + 59' + 60"
--------------------------------------
93 degrees - 63 degrees = 30 degrees
59' - 43' = 16'
60" - 12 = 48"
--------------------------------------
The answer is:
30 degrees 16' 48"
