Your answer is the second statement, Angle D is an exterior angle because it is not inside the triangle. This is because exterior angles on any shape are angles that are not included in the shape, but are rather attached on the outside. I hope this helps!
I think the answer is D. The other answers are unreasonable. Wyatt would not get the promotion and just because Tammy's lowest value is bigger than Wyatt's doesn't mean that Tammy gets the promotion. The only reasonable answer is D.
