Answer:what are all the choices
Also it’s 0
Step-by-step explanation:

That is the formula to find the slope. Hope it will help you.
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
