We know opposite angles in the parallelogram is congruent:
let x to be the unknown angle:
360=2(110)+2x
360=220+2x
140=2x
x=70
ECF is also 110 because of parallel lines and corresponding angles:
110+x+y=180
110+30+y=180
y=40
so DAE is 40
Answer:
d = -8
Step-by-step explanation:
Isolate the variable, d. Note the equal sign, what you do to one side, you do to the other. Divide -4 from both sides of the equation:

d = -8 is your answer.

Answer:
base = 2 m; height = 6 m
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- base of 8 meters
- height of 6 meters
- top side length of 4 meters.
=> the height of one of the triangles equal to the the height of the trapezoid = 6 meters
=> the base of the triangles:
= (the base of the trapezoid - the top side length) / 2
= (8-4)/2
= 2
So the base and height of one of the triangles : base = 2 m; height = 6 m
Hope it will find you well.
