Answer:
The sum of the exterior angles of a polygon is always 360 degrees, regardless of the number of sides. So, if we know the measures of two exterior angles, we can find the measure of the third exterior angle by subtracting the sum of the first two angles from 360 degrees.
In this case, we know that the measures of exterior angles R and P are 80 degrees and 72 degrees, respectively. So, the measure of exterior angle W is

360 - 80 - 72 = 108 degrees

Therefore, the missing exterior angle is 108 degrees.
