Can we have the answer choices please?
I would say the answer is B my good sir
<u>Supplementary:</u> N and M & N and I
Supplementary angles: A pair of angles whose sum is equal to 180°.
<u />
<u>Vertical:</u> M and I
Vertical angles: A pair of opposite angles that are made by two intersecting lines.
<u>Complimentary:</u> None
Complimentary angles: A pair of angles whose sum is equal to 90°.
Hope this helps! :D
On the added picture you can see that graphs of functions

and

have two points of intersection. The x-coordinates of these points are the solutions of the equation

.
Hence, the approximate solutions are x=-1.9 and x=1.6.
