Answer: We can find out the missing statement with help of below explanation.
Step-by-step explanation:
We have a rectangle ABCD with diagonals AC and BD ( shown in given figure.)
We have to prove: Diagonals AC and BD bisect each other.
In triangles, AED and BEC.
( By alternative angle theorem)
( Because ABCD is a rectangle)
( By alternative angle theorem)
By ASA postulate,
By CPCTC,
and 
⇒ BE= ED and CE=EA
By the definition of bisector, AC and BD bisect each other.
(A) SAS
<u>Explanation:</u>
According to the figure,
One angle of both the triangles are equal
Two sides of both the triangles are equal
If two sides and one angle are equal, then the given triangles are congruent to each other.
9 x 6 = 54 is this right I'll do distributive property next time
Answer:
x = 6
Step-by-step explanation:
A = 1/2bh
36 = 1/2(12)(x)
x = 6
First you had to add by twenty-two from both sides of equation form.

Then simplify by equation.

Next, you divide by four from both sides of equation form.

Finally, simplify by equation.





Final answer: 
Hope this helps!
