Answer:1. 7 2. 
Step-by-step explanation:
1. 
= 7
2. ( doesn't have any simplest radical form)
Let's see
In ∆ABE and ∆CBE
- BE=BE(Common side)
- AE=EC[Diagonals of a parallelogram bisect each other]
- <AEB=<BEC[90°]
So by
SAS congruence the triangles are congruent
AB=BC
Fact:-
It's already given AC is perpendicular to BD
- It means diagonals are perpendicular to each other
According to general property of rhombus this parallelogram is also a rhombus.
So sides are equal hence AB =BC
Answer:
Addition Property of Equality
Step-by-step explanation:
You are adding 3/4 to both sides to isolate the <em>x</em>.
Answer:
