Answer:
F, D, E
Explanation:
Alright, try not to overthink it. During a reflection, nothing about the triangle changes other than it's location. The sizes of each angle STAYS THE SAME.
This means that angle A=D, angle B=E, and angle C=F. This also means that angle D=40 degrees, E=105 degrees, and F=35 degrees. Now just rank them from least to greatest, which would be F (35), D (40), and E (105). Hope this helped!
