as AB || DE then
angle BAE = angle AED
so angle AED = 70
as AD = AE then
angle AED = angle ADE = 70
now in a triangle
angle DAE + Angle ADE + angle AED = 180
angle DAE + 70 + 70 = 180
angle DAE = 180 - 140 = 40
Ummm explain the question more but b seems to make the most sense
Answer:
B
Step-by-step explanation:
9 multiple 2m = 18m
9 multiple 5n = 45n
9 multiple 10= 90
