Answer:
40% increase
Step-by-step explanation:
c = final value - initial value
------------------------------------
initial value
112 - 80 = 32
32 / 80 = 0.4
0.4 = 40%
now, keeping in mind that 1 degree has 60 minutes, and that 1 minute has 60 seconds and therefore there are 60*60 seconds in 1 degree, or 3600 seconds.
72°22'30", has 72 degrees, plus 22 minutes and 30 seconds.
or 72 degrees plus 22/60 degrees plus 30/3600 degrees.
