In other words the exterior angles add up to one full revolution. The exterior angle is 40° + 27° = 67. After repeating the process fo. An exterior angle is supplementary to its adjacent triangle interior angle.

For example, if we have the exterior angles 60°, 70°, 80°, and 85° in a pentagon, we have to start by determining their sum and then subtract it from 360°: You can solve for y. The measure of the missing angle is 65°. If you already have the other exterior angle measurements, you can use those to help you find.

It explains how to use it solve for x and y. The interior and exterior angles add up to 180°. Let's try two example problems. The exterior angles, taken one at each vertex, always sum up to 360°. Once you know what the angles add up to, add together the angles you know, then subtract the answer from the total.
