I will base the figure from the one you attached in the other problem you posted. (Also attached here).
Statements [Reasons]
1. Angle X is congruent to Angle Z [Given]
2. Line XY is congruent to Line YZ [Given]
3. Angle Y is congruent to Angle Y [Congruence is reflexive]
4. Triangle XBY is congruent to Triangle ZAY [ASA]
ANSWER: The ASA (Angle Side Angle) Congruency Theorem could be applied.
Answer: 33.041666
Step-by-step explanation:
Given: The translated equation : 
To find the value of x if y = 87.5, we need to substitute the value of y in the given translated equation, we will get

Subtract 87.5 from both the sides , we get

Now, divide 300 on both the sides, we get

You add the numbers 69 and 59 and you get your angle measure.

Answer:
The answer is D: Yes, BD = 7 and CE = 7
Step-by-step explanation:
B--> -5
D --> 2
-5 + BD = 2
BD = 7
C--> 0
E --> 7
0+CE=7
CE = 7
The answer is D
