To get the answer we have to subtract 252 from 180*3-180=360
3 times 180 its because it represents 3 exterior angles and minus 180 because its triangle interior angle.
360-252=108 its the answer

The sum of the measures of two exterior angles of a triangle is 252. What is the measure of the third exterior angle?
