AE and EC are congruent because it's given that E is the midpoint of AC. However, DE and EB cannot be congruent because it does not state that point E is the midpoint of DB.
You cannot assume that all the triangles DEA, AEB, BEC, and CED are all congruent just from being given that E is the midpoint of AC. You would need to be given other information such as "Quadrilateral ABCD is a parallelogram. "
idk what a special parallelogram is but a square is most definitely a parallelogram :)

Answer:
Proved!
Step-by-step explanation:
Since TS is a tangent to the circle, ∠TSO = 90°.
Hence, ∠OSR = 90° - x.
Since OS and OR are radius, OS = OR.
So, ∠ORS = ∠OSR = 90° - x.
Thus, ∠ROS = 180° - ∠OSR - ∠ORS = 180° - 2 * (90° - x) = 180° - 180° + 2x = 2x.
So, it is proved.
Answer:
A. 3
B. 4.5
Explanation:
A. 2(5x - 3) = 24
10x - 6 = 24
then add six on both sides
U get 10x = 30
divide 10 on both sides
U get x is 3
B. 5(2x + 1) = 50
10x + 5 = 50
minus five on both sides
10x = 45
divide by 10 on both sides
The answer is x = 4.5
