D. supplementary​

Answer 1

Explanation:

D. supplementaryAn exterior angle is an angle that is supplementary when any of its side-extended with an interior angle of a triangle. In other words, when you extend one side of a triangle, you create an exterior angle that is adjacent to and supplementary (adds up to 180 degrees) with the interior angle next to it. This property is true for all triangles.
