Answer:

Step-by-step explanation:
(5,9) and (2,3)
then by distance formula

d²=3²+6²
d²=9+36
d²=45

Answer:
115mm
Step-by-step explanation:
5/x = 3/69
5/x = 1/23
5*23 = x
115 = x
Answer:

Step-by-step explanation:

Answer:
cookie=0.5, popcorn=4
Step-by-step explanation:
1x+2y=5
1x+4y=6
cookie cost 0.5
popcorn cost 4
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
