M= -6
-6 + 8 = 2
4/2 is the same thing as 4/2 Lol
The exterior angles on this diagram are angle 4 and angle 2.
We can see this because an exterior angle is the angle that forms a straight line with an interior angle, so that 180 - [interior angle] = [exterior angle].
Therefore, angles 4 and 2 are the only angles that form straight lines with interior angles, so they are thus the exterior angles.
I hope this helps!
Step-by-step explanation:
