Alright so we know that measure of angle AED can be found using sum of triangle theorem how! Since we have 2 known angles in triangle AED we can certainly find the 3rd angle named AED So 90 + 36 + AED= 180 126 + AED = 180 AED = 54 So we so far found that 1) measure of angle AED = 54 2) Justification: triangle sum theorem And we know that ECB = AED By corresponding angles theorem So 3) corresponding angles theorem So the option would be D
