Each exterior (or outside) angle is 180 degrees minus the measure of the interior (or inside) angle.

by the exterior angles theorem, the measure of an exterior angle of a triangle is equal to the sum of the measure of the two opposite interior angles of the triangle. So, the exterior angle of C for triangle ABC is the sum of angles A and B.

taking forgranted that you menat the exterior of the triangle whose one arm is extended, it is (180 minus interior angle) or the sum of other two interior angles.
if there is no extension in arms, the exterior angle is reflex angle with a value of 360 minus interior angle of the same vertex.

Unless it is equilateral you can't find each angle. But their sum will always be 360 degrees.
