They both are 180 degrees.
One possible difference is that a straight angle is just a single angle measuring 180 degrees, while a linear pair supplementary angle are pairs of adjacent angles that add up to 180 degrees.
-19.2
12/(-5/8) means 12*(-8/5)
12*8=96
96/5=19.2
don’t forget the negative sign
so
-19.2
