7x-23+11x+23=180
4x+0=180
4x/4=180/4
X=45
Answer: x=45
Kidjov the answer I came up with for you is 792 I hope this helps
divide the points by the multiplier 1.9
so 3.8 /1.9 =2
the base score was 2.0
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
