A) 24 because it a very simple
True, bc they add up to 180 and are the same size.
Tough call.
You may have to use Newton's Method or something like that.
Graph y=2^x and then graph n/x on the same set of axes. You may have to assign some arbitrary value to n to make this work. From the graph you can read off the approximate coordinates of the point of intersection.
Y=-2/3x-1.3 (0,-4)
