We have that AB || DC.
By a similar argument used to prove that AEB ≅ CED,we can show that (AED) ≅ CEB by (SAS) . So, ∠CAD ≅ ∠ (ACB) by CPCTC. Therefore, AD || BC by the converse of the (
ALTERNATE INTERIOR ANGLES) theorem. Since both pair of opposite sides are parallel, quadrilateral ABCD is a parallelogram
1. AED
2. SAS
3. ACB

Answer:
x = 9.3
Step-by-step explanation:
tan 25° = x/20
0.4663 = x/20
x = 9.3
Adding a positive to a negative, you would look at the number with the greater absolute value, and that number would determine the sign of the sum.
