Can someone check my work?

Find the complement/supplement of 14º12'

To find the complement I put:
90º0' -> 89º60'

89º60' - 14º20' = 75º40'

To find the supplement I put:
180º0' -> 179º60'
179º60' - 14º20' = 165º40'

I know I found the complement part correctly, but is finding the supplement the same concept? I know it's a silly question but I want to make sure.

Thanks!
