You can put this solution on YOUR website! The sum of the measures of two exterior angles of a triangle is 271. What is the measure of the third exterior angle?
---------------------------------
The sum of the exterior angles of any convex polygon is 360.
EQUATION:
Let the 3rd angle have measure "x".
271+x = 360
x = 360-271
x = 89 degrees
