it gave you part of it so subtract that off . 111 - 72 = 39 degrees
10 times what equals about 39 degrees.
39/ 10 = 3.9
I hope this helps you
z^3+5z+3z^2-4-2z^2
z^3+z^2+5z-4
Lets say our problem is 12÷24 which ofc equals 2, well we could figure it out by thinking hmmmm what is 12 x __ that equals 24?
